Thank you very much for your help, much appreciated. I have actually ordered a copy of "Medium Format Cameras: User's Guide to Buying and Shooting" which I hope will provide some more in depth information. At this stage I will not be able to develop the pictures at home, however in the future this is something I would like to get involved in. Having looked at various webstes it seems purchasing a Bronica would be a good starting point, are there any advantages in buying either the ETRSi or SQB ?
