Switched to Bittrex as well but about a week ago I sold some leftover coins I had on Cryptsy and bought some AUR and it took me 7 withdrawal attempts to get all the AUR out as I would only get 6-900 coins in each withdrawal. I guess you only get what is in their hot wallet at each time which is a percentage (my guess 5-15%) of what they have in total. So that you are only getting 200-300 coins in each withdrawal means that Cryptsy has very little Auroracoins left. People are moving to Bittrex.
