I would consider either the 533MC or 294MC. I shoot mono with the 294MM with a similar refractor, but was about to get the 533MC until I got the 294MM on here used for the same price as a new 533MC. The 533MC is a great camera, but some people don't like the square sensor. If that doesn't worry you then go with the 533, otherwise the 294 is a good option.
Cheers,
Mark
