I must be the only person who actually likes Cryptsy. It works well for me, and the fees are reasonable. The only problem I really had was with the 502 error, although that seems to have improved. I've found I sometimes get issues if I try to have multiple tabs loaded for different coins, but if I just have Cryptsy in on one tab, it's really stable. Sure, stability could be improved, but all in all, it works, and I haven't seen anything better, especially with that range of coins.
