A couple of years back I picked up a Superior TV11 tube tester on eBay for $40 or $50. Not the fanciest tester in the world (it is just an emission tester) but it works for my purpose.
If you decide to buy a tube tester I would recommend you educate yourself about the different types and watch the auctions so you can bid intelligently.
