I too prefer the Vb, but if I didn't already own one and I had need of a good TLR for travel and general image making, the Va would be fine. It has the adaptable format (12-16-maybe even 24-35mm) and all it's lacking that I would miss is the removable WLF - I'm at an age where the Rollei prism has become a must for fine focussing, so the prism stays on my Vb most of the time.
It looks nice and clean, and as the OP has written, it's had a service. Win-win throughout.
The price also seems eminently right for a camera of this quality.
