Go with the Hassy! I bought an older 500c, back, and 80mm lens two years ago and it is amazing. I too know the pain of looking at hassy lens prices, so here is what I did. I have a 2x converter, which gives me a 160mm lens wit only one stop of light loss. I have a set of 3 close up filters, and a 55mm tube for doing macro. I did add a second back to my kit. When I do win the lottery, I'll look at getting the 250mm, and the 40mm. It seems when ever I get close to saving the money for another lens, a Linhof, or a Veriwide walks by, and I can't resist. I just need to learn to keep it in my pants, my wallet that is.
