Primo Tenderizers how much

How much are Primo Tenderizers what do they look like?
Anyone know a UK Site that sells them on the cheap?

They’re usually about £25-£30 depending on what you want, though you can go crazy and spend more on some models. Er, I got mine from an RS in Leics, but may have them. Most BMX shops will have em.

There’s a pic on US.
