This thread caught my eye as I'm thinking similar things. I got the graflex (which I'm trying to debug focus issues..that's another thread) which I like but at some point I know I'll want a better 120mm and will be looking at the options discussed here. I've always liked the Mamiyas and I've seen some packages on KeH (a well known dealer in the states.) If there is a similar type of dealer in the UK I'd look and see what they have as you have someone standing behind it...not the case with "the bay."
