I've found an LGR at DAI leisure via Gunstar.
Apparently it's immaculate and seals fine.. The only thing is it's listed for £500 and that puts it up against a lot of other secondhand equipment, - FWB 600 and C60 can be found cheaper.

I've got a couple of questions,

Is it worth it? Or would a FWB be better for the money?

As it's a couple of hours away, does anyone know this gun and is it a good shooter?
