To me, it's all about how the horn plays. If I found a great playing VI, I wouldn't care so much if it was relacquered or not. As a bonus, you can probably purchase it for less as a relacquered horn, since relacquer jobs affect the perceived (and someimtes actual!) value of the horn.
FYI, I have a MarkVI tenor which I had relacquered a few years ago. I am a working pro, it is my main horn, and I will never sell it. You can hear it if you visit my site (see sig).
Oh, don't let the MarkVI mystique get to you - not all VIs are great. Try to asses it as objectively as you can. What good is it to say you have a Mark VI, if it doesn't play great?
Good luck!
