ic apex 20ke fpga 200k 484-fbga - Help

They did become very interesting to me after I looked them up on Digi-Key, very pricey to say the least. I'm a fish out of water as I drifted into this forum this morning. I have no experience with these nor the knowledge of popularity. I am aware that although they seem to have nice value after researching them, there's always the chance it will sell like a cisco router does after three years goes by. I guess the date code not being expired made me think these were more current than what I usually find and may be sought after parts. Any information I get from you is very helpful and appreciated. Hell, I feel like I really accomplished alot hooking up with the 2nd highest and well respected person on this site. I was hoping for results and that's exactly what I found. So I guess I'll just list them on ebay and see how they do. Thank You sir.
