I think old Acer 6011s might be one of the safest bets for solid white Alps switches, and some variants have the same case as the KB101A and look practically indistinguishable aside from the FCC ID and model number (as does the Acer 6311-K with Acer switches).
Old Acer boards seem pretty rare, though. Almost as much as the KB101A itself! The only ones I've ever seen in the last few months on eBay are things like these: http://www.ebay.com/itm/ACER-PS-2-AT-STYLE-VINTAGE-PC-COMPUTER-KEYBOARD-5-pin-DIN-6311-/251781340122?hash=item3a9f565bda:g:RHMAAOSwg3FUqcqL
BTW, E3E, do you have any Blue Alps keyboards on your radar? Or cheap White Alps boards that can be harvested? Chyros did recommend asking you to another poster earlier on this page. 
The last blue Alps board I'm really hankering for to complete my blue Alps dynasty would be an Acer KB101A. I wouldn't mind any blue Alps board I could find though; I just like collecting blue Alps stuff! I was half-hoping the DC-3014 would've come with Brown Linear Alps. I have my linear Brown Alps thanks to a trade with sth that I've made. Still waiting for a full board with them. I have pondered swapping the blues out of my DC-3014 and adding SKCL brown instead, but eh. It is quite a nice board to type on, especially with the AT101's caps on it.
So pretty much, as far as blue Alps are concerned - KB101A and any little interesting blue Alps board, butt I won't go out of my way for many right now. I'm very much happy with what I have! The only other one would be one of those replacement Apple IIc boards with SKCM blues and Alps branding on the top housing of the switch.
As far as I know, that's the ONLY keyboard that has that contains blues with the Alps branding like that.
Some curiosities I'd like are the Focus FK-767 which also exists in a variant form for the Philips PM 3655 Logic Analyzer, though it seems like that one might only have Omron Cyan. No idea though.
Another would be the variant of the Chicony 5170 with blue Alps.
An Ortek MCK-101 would be neat to have (since it looks so similar to the FAME except all plastic and a few small differences, but more so than the Chicony 5161), but that falls more under the "little interesting blue Alps board" stuff and not really something big for me. This one can come with white Alps too, though, as can the 5170.
Also, before you make a potentially horrible mistake; the DC-3014 did NOT always come with blue Alps; in fact, it's much more well-known for being able to come with linear brown Alps (which are far rarer). The one you might be thinking of is the DC-2014 
.
Horrible mistake? Pff, brown linear Alps are fantastic switches and fantastically rare. It wouldn't be a mistake at all! If I were you, buy any DC-3014 you can find. They are fantastic, have NKRO (the only ANSI blue Alps board to have such a feature), and an excellent, incredibly solid build quality. Made by Daewoo in Korea.
Now about blue Alps not being rare--this is true, at least in comparison to SKCM green and SKCL brown. They are less common than the other types. SKCM amber and SKCM brown are always around, it's just hard to find a source with a decent price tag. The main thing about blue Alps that makes them hard to find is that there are hardly any surefire sources for them where you know you'll get them every time.
AFAIK, only the Leading Edge DC-2014 and the NEC APC-H410 (84 key, not the 101 ANSI board, which is the H410E) have blue Alps for sure--that are common-ish anyway.

Yeah, right now, they are very VERY desirable, so anything you see on the market will be a flash in the pan in terms of how long it stays there.
As an interesting note, a seller on taobao relisted the very same Monterey K101 I have with the same exact serial number:
https://item.taobao.com/item.htm?spm=a230r.1.14.106.I5IAKh&id=41551316167&ns=1&abbucket=20#detailBe sure to try and buy that paradox of a board! Let's see what happens!
My greatest blue Alps blunder was passing up 100 blue Alps switches + a keyboard thrown in as a bonus for a total of $16 USD before shipping on TaoBao because I was stuck on a technicality and couldn't decide.
