I have a like NEW Yellow Westhold Transponder Kit which comes complete with charger and holding pouch for the race car. Many tracks charge a Rental fee for use of theirs, but all you need to do is give them your Transponder # and you're all set! This Unit works perfect and was used 3 times, only because we didn't continue racing.
The KITS sell New for $240. Transponder by itself sells for a little over $170 I'll take $175 plus shipping for the entire Kit.

PM me your contact info and method of payment.

Thanks.
