88 for a Va - wow, lucky you. I paid 190 Euro for a good looking V and then had it serviced for 250 (including some parts which needed to be replaced, mirror and ground glass cleaning etc). In the end it was all worth the money as a TLR is a lot of fun.
As to GAS, the good thing about the Rollei TLR or should I say about most TLRs: No need to spend money on lenses. And there are not too many accessories you can get - well, some filters come in handy whereas a lens hood in my opinion is not an accessory but a must.
I was thinking to send it to Braunschweig for CLA. Do you have any other recommendation?
