I've recapped about 30 TV's in the past year or so, only restuffed the caps in two of them. One was my Transvision kit just to see how much extra time it would take (lots), the other a pre-war set which is the only way to go (IMO).
I had two pre-war sets come in to the shop for restoration, the owner just wanted the caps changed he didn't want the extra expense of restuffing. The customer is paying the freight so whatever they want, they get.
As far as cabinets go, a good refinisher/woodworker is a must to have on hand, it is amazing what they can do. Here's a link to one of my projects from a few years ago:

This cabinet was a "basket case" it sat in a barn first, then at the auction they let it sit in the rain. The work wasn't cheap, but it was worth every penny.
If someone pays $2500 for that Transvision on Ebay you can bet I'll send my Transvision cabinet out in a heartbeat.
