Yeah I just paid $50 or more for a couple reconditioned ones online after I got tired of watching craigslist, sounds like a great deal to me. Still waiting for mine to come!
You can buy a set of o-rings for $5-10, as Greenbasterd mentioned, or check out the sticky in the "equipment" section with links to buy them in bulk on McMaster. You can spend $30-40 and have enough seals to last you a lifetime! Enjoy kegging, I can't wait to get into it.
