I would also add, as I have said before, that unless someone can do the recap themselves, it really only makes sense to recap higher-end/closer to TOTL pieces. For less expensive pieces, it's more sensible to clean them and then just use them up until they go bad, and then replace.
Except the near TOTL or TOTL pieces are usually much more expensive than the next model or 2 down. How many Sx 780's can you buy for the cost of one SX 1280 (or whatever the TOTL SX series is)?
I had a Sansui 8080db that was less than half of what a 9090db of similar quality went for and I'd bet the cost of both of them that the 9090 didn't sound that much better (frankly, I'd bet it didn't sound any better but that's a different thread).
