I have been in contact with a company called NWP Engineering, Inc.

I want to keep it short because alot of info has already been posted..

For cost we are looking at about $175-205..

All this thread is for is to collect interest and if there is enough interest he will begin to produce them and look into becoming a forum vendor for clubs that show a good interest.

Here are all the details:

(sorry to link over to another forum but there is a TON of info about these on that thread)

Just post up here or there if you are interested at all.

Thanks
Chris
