Absolutely worth every penny - I got a Saturn late in the game when they were being sold new at Electronics Boutique for like $20, along with a bunch of clearance games (MKR for $15, heh. Should have bought more).
Get yourself a Pro Action Replay 4MB cart and pick up imports - U.S. Saturn releases weren't terrible - lots of good stuff came over here but a lot of the epically good Japanese 2D stuff never made it over (Keio 2, Pychic Killer Taromaru, a million RPGs, Capcom fighters, etc).
Unfortunately, U.S. prices have been going up a bit recently...stuff like Shinobi Legions is selling for 3-4x what it was a few years ago. Imports can still be had cheap for the most part if you have a good source.
