I think functionality comes first, then comes the price. It depends on your applications. As far as DSP applications are concerned (in general), Xilinx Spartan-Virtex devices are the most suitable in my opinion. Reason: 1- Large amount of memory on-chip (see BlockRAM in SpartanII and Virtex devices). 2- Efficient implementation of delay queues (see Synchronous distributed RAMs) 3- Fast carry chain (fast adders---> Fast multipliers) Ray has explained that many times in this NG with a comparison with Altera devices (Flex10K - Apex). Make a search in deja news. Spartan-II is a cheap version of Virtex devices with some features removed (e.g. assynchronous BlockRAMs). But you probably do not need these features anyway. I believe that the prices are < $10 a unit. Check it out with Xilinx. I am not a Xilinx representative. Their devices are really the best as far as DSP is concernd. The software has developed drastically though there are still some pitfalls. The support is also good. Hope this helps!

The LUT-RAM writing became synchronous in the olden days of XC4000-E. Much nicer, so you don't have to time the write pulse so tightly. The Virtex temperature-measuring diode has been traded for a power-down input in Spartan-II. And the available packages are quite different.
