I just had my fork seals done last year, I think the cost was 275$. But I'm in god's chosen land, the land of cold beer and hot barbeque.. Austin, Texas! When my mechanic told me the price, I said "wow" and he started to justify himself.. and then I said, "I thought it was going to be a bit higher!" Caveat: he's an independent mechanic, not a shop guy.
I'm pretty good with valve adjustments and whatnot, I don't know if I'd tackle either of those jobs though.
