bter.com is brand new and unknown, hard to read, with large withdrawal requirements.
cryptonit should not be used due to measures which are a standard for recordkeeping that they simply ignore.. I.E. If they crash they may not know how many coins belong to whom.
Just putting a fair warning out there, search the form for my reasons why
I tested bter with 100FTC, went fairly smooth, processing took long, and you can only withdraw whole BTC's 0.1,0.2,0.3.
