does anyone know where i can get a cheap dual back box,
i know sportex do one for £199, anyone know of a cheaper one?

I have the dual sportex bak box sounds well nice mate, I think its about the cheapest around got mine off ebay for about £165 inc postage if I remember rightly keep an eye out some go for about £130 on there then £15 postage now you wont beat that for value for money or else you get a secoundhand scorpion or mongoose. P>S powerflow cant do one that cheap as far as am aware either

nope powerflow will be more expensive like you said.

Check out the Peco ones. not to bad prices> although Id say the sportex one was better.

Sportex one on ebay now.
