There are used units out there. Finding them is the challenge.

One source of a lot of advertising by dealers and some private individuals is the National Dragster. This is the weekly publication of the NHRA. It is well known in the drag racing group.

The first issue of this race season just came out after their 4 week winter break. There are 12 pages in the classified advertising section. Included are dealers, manufacturers and individual ads. You could probably come up with the names, phone numbers of 8 to 10 dealers. Contact them and you might find a used unit.

Also contact the manufacturers and ask for a list of their dealers. Then contact the dealers to see about used units.
