"Gates" is largely a meaningless number for FPGAs. A "200,000 gate"
Spartan device is, however, enough to implement a pretty sophisticated
project including several microcontroller cores.
FPGAs range anywhere from "15,000 gates" (400-ish LUTs) to tens of
millions; price varies accordingly from single to four (or five?) digit
numbers in U.S. dollars.

Is there much difference between a spartan 2 and 3 if its for relativel
small projects? Is a virtex product a major step up?
Secondly is 200K gates very small for a fpga? I know you coul
implement alot in 200K on an ASIC - but i persume its a completel
different story with an fpga
