amb handout transponders

[tamiyaterror]

hi all, we have just started a new club in our local area, and are currently looking for a complete set of amb handout transponders (must be amb 20 to work with our software). we currently have some, but out of the 16 we have, only 8 work!, which means they are constantly in use. let us know what you have, if your a club packing up or simply upgrading to pt's let us know. we would consider anything.
