A good deal if your happy with it. I would [at this point] no longer buy anymore G3's; unless you plan on using them for internet use, or just email, or iTunes.
If it was me I would have boughten the oldest G4, which the new OS will be able to run on, if you wanted to have a cheap Mac. However, G3's are still great computers, but it just doesn't seem like a good buy in this day and age.
