Buying cheap 50s in multiple playlists.

I'm looking for Halo 3 accounts that have multiple 50s. I can pay by PayPal or codes but I'm not paying alot.

Playlists that I'm looking for 50s in:
Slayer, Doubles, Swat, Snipes, MLG.

I don't care about the record or if its Silver. Just need an account for cheap with a 50 in 2 or more of those playlists.
