I'm looking into LF cameras.

I'm not sure which I'd pursue but the Super Technika IV and V are on my list.

1. How easy is it to get one of these serviced? What about bellows? What is the rough cost? I know that Leica's and Rollei's for instance are easy to get serviced (maybe not cheap...) and there are many options but I have no idea how it works for these cameras.

2. How easy is it to get one of these things cammed? I belive that the IV needs to have a matching lens/body but the V is interchangeable. How much does it cost to cam a lens?
