Thanks again for your advises.
I did the maths on KEH, and reached $510 (I considered $80 per lens, as there weren't the same ones) without the tripod.
I've been looking at tripods as mine are a bit cumbersome, so the 190 might be a good deal (I even consider shortening it a little to make it lighter !), and my 055 and Berlebach are enough for the other cameras.
The paramender is a "must have" for me, as I do lots of close-ups in MF, I'm not so sure about the screens.
Last, I'm used to print 6x6 as a square and, should I buy ths 330, I plan to do the same, so the aspect ratio is ok for me.
I'll keep you informed when I have made my decision and inspected the kit.
