Hi Big ten,
Welcome to MFK! I think I saw your post on CL. I haven't seen any 8-10" silvers in a while. Mr. Aqua on Alameda used to have some at a great price, but I think they might have closed down. Fish Palace has a giant one, but I believe it's over priced at $250. Check in with Golden Fish Aquariums on Colfax and Wads periodically as they tend to get silvers often. I got a 13" silver a while back from them at a good price. Fish palace has some smaller 3" silvers for $20 and Hart's corner has some 5" for $50.
Good luck!
