A properly serviced Rolleiflex will give you a camera good for the next 40 years. Look for a T or an Automat from the '50s. Both seem like good bricks. I 2nd the ETRs line if looking to stay on a tight budget. It is a workhorse with 1st rate lenses and a good range of focal lengths. It has multiple backs and finders as well as grips so it can handle almost as you please. A one lens kit in excellent can be had in the $200 range.
