dont buy from grabcart, they dont deliver, see the previous page in this thread.
I just spoke with dsi yesterday on the phone, looking for an smk85. They told me pretty clearly: they dont have any, not even 'in the back'. They dont have any refurbished ones either, not even on ebay. They also told me they will not be manufacturing any more boards with alps switches, they're all cherry now. The modular mac (on their website) has replaced the smk in their lineup (it uses cherries only). And while they have some plans to bring out an additional compact board in the next few months, it too will have cherries, not alps.
What this also means is that grabcart's listing of "new" smk85's, is FAKE. They dont exist anymore, certainly not in new inventory like that.
