Hi, I'm going to steer you to this huge post about the Rubicoil:
Forums at Splitcoaststampers
There are some links in there for places to buy, but it's also a WONDERFUL source for ideas with the thing.
The three main places listed are Coil Connection, Laminator Warehouse, and a third one -- dumb, I ordered from the third one, too, and now I can't remember the name! Sheesh...
Anyway, the approximate cost varies...Lam. Warehouse offers the thing all by itself for $139. The tools and coils are separate.
Coil Connection also sells it, at a higher price, but she offers a selection of coils in the package.
The third place mentioned in there is having a special that includes the Rubicoil, the crimper tool, $24 worth of coils PLUS a cd player, for $164 or something like that. You can see what a savvy shopper I am...I am really fuzzy on these details!! However, read through that thread...you'll see all the places listed...
