I just put a 46T on the instead of the 50T - it's much nicer. I got one from Spa. It's quite a bright silver but the chainring seems fine, it's a rebranded stronglight ring. I needed to file down the peg slightly so it wouldn't foul the crank arm.
You can get a 33T inner ring if you really want, TA do them.
Eurgh. So you may as well buy the CX50. It's basically a fc-5750/fc-r460 crankset with appropriate chainrings already. You may want to pop a 34T in there instead, but those are easy enough to find. The fc-r460 and fc-3550 can actually be found with a 46-34 set already.
