Nope. But if you like it, and it's otherwise in good shape, spend a few bucks on a refret. Shouldn't cost very much--assuming it's not a maple neck, and there is no binding on the edges of the fingerboard, both of these items raise the price a lot.
And hey, when it sounds like crap, change the strings! That's a sure-fire cheap fix.
And while you're at it, buy yourself a new guitar too!
