McCormack REV B upgrades. Better than a new amp?


I have read the testimonials about the stellar performance of upgraded versions of McCormack amp,especially the "REV B" level. A "used good condition" McCormack DNA-1 bought for 750.00, with REV B. upgrades added later is approx 1600.00 with round trip shipping costs. Would it make more sense to find a another amp that is newer, though USED between $1200-1500?? Also, do the McCormack upgrades hold up over time??

Old thread but related question.
Have  an opportunity to buy a DNA 0.5 rev B. 2nd Owner  and does not know when the rev B was done.  Was talking to an eng at CJ (CJ have taken over support for McC) and he told me that after 20-30 years, some of the caps have to replaced.Is it worth buy this DNA 0.5 with rev B given that the rev B was probably done 20 years ago?I am planning to power my Vandersteen 3a signatures. I would have preferred DNA 1 or DNA 225 as they have more pwer but harder to comeby.
My alternative is to buy a new MF integrated  for around 2K.New Belles Aria separates would be a very fantastic fit for my Vandys 3a  but they are $4.5K and out of my budget
