Thanks Alan, I have now pretty much settled on the Bronica ETRSi, as you said it seems like a good one to start out with, and being on a budget I can't really consider anything like the SQ series. Also the ETRSi is a fairly recent camera compared to others.
I think the ETRSi would be best for me right now, there are a lot of lenses and accessories around so I think it would be the most logical camera that has been suggested for a beginner like me!

Thanks again
