yeah, I haven't personally owned a Rosewill but based on pics and reviews I think Oqsy nailed it - there's an ugly logo and reports of some out of box controller weirdnesses, but other than that, the only reasons I haven't bought one are a) they don't come in clears and b) I need another keyboard like I need a hole in my head.
Of course, I just preordered a Leopold, but that was primarily because I don't have a tenkeyless, never had a Leopold, and I feel obligated to show my support of a manufacturer that's actually making plate mounted clears available.
I'll be disappointed if I discover that the rumors of the Leopold/Cherry stabilizers being less desirable than Costar turn out to be true, but even so, they and Deck are pretty much the only options. And of course I do have a Filco that I already modded because I didn't know this was going to happen. If you are looking for tenkeyless (or even if you aren't) Leopold is certainly another option to consider, they've been selling blues for a while now.
