How about reconsidering the 'no rangefinder' decision if you want good value? In particular the Mamiya Press - the Super 23 or the Universal. These sturdy rangefinders have some good features for the money.
The 50 mm, 75 mm and 100/2.8 lenses are very good.
The well-designed film holders are available in 6x9, 6x7 and vari-format.
