The old metal Calumet 400 series monorails are excellent values. They aren't the best for backpacking but that isn't in your criteria.

If back packing is in the cards, you'll probably prefer a wood clamshell folder. There are quite a few new ones coming out of asia and some are enthusiastically recommended by others more knowlegable than myself.

A good 1st lens is a 210mm, sometimes you'll come across a 203mm Ektar for under $200 and thats a real steal IMHO. If your serious about architecture sometime you'll probably want a 90mm Super Angulon.

Accesories? Light meter, tripod, film holders, filters, cable release, dark cloth, focusing loupe.

I strongly recommend getting a copy of Steve Simmons Using The View Camera before buying any gear.

Have fun!
