You first have to define "tight." A TLR is always the least expensive way to go. You also have to decide what format you want to shoot. If speed is your most important criteria then a 645 with built-in meter and motor drive is fastest. My favorite is the Pentax 645 as it is the most compact, lightest in weight and most automatic of the 645 systems. If you want interchangable backs then the Mamiya and Bronica would be what you want at the cost of increased bulk and weight. If image quality is more important to you then you have to look at 6x7, the best being the Pentax 67 for handheld and the RB/RZ for studio/tripod work. No MF system is expensive compared to what it was 10 years ago so what you ultimately get depends on your needs or wants.
