hey man, I have been on the verge of buying a 512 stick for months (waiting for my 'flo' situation to stabilize). Anyway, I have been watching the Samsung's at MemoryX and it seems as tho the price has actually gone up about $20 during this period (unless I'm mistaken about my recollection re: the original price). I think that they are selling for around $180 right now. I know that you can get a 512 stick from other manufacturers for around $125, but I think I'd like to stick w/ Samsung.
