Lafayette TE-50 Tube Tester, $70

Simple tube tester, in good condition.  Includes an 18-page list of settings for various tubes. 
$70.  Shipping and PayPal fees included. 

Here's a copy of the manual:

I've successfully used this unit to test common tubes, to determine if the tubes are functional and operating within spec (though it's not clear exactly what those specs are).  Obviously this is not a real sophisticated tube tester, so if you want to compare the transconductance of the four tubes in that matched quad, this isn't for you.  But if you want to know if the used tube you just bought is functional, or if a tube in your amp or preamp just failed, this will probably do the job.

Lower price.  And if you have something to trade (in particular, a reasonably good power cord, or isolation cones), let's talk trade.
