on this forum! people will snap up this offer, but for £150, i advise you go for an a-5, slightly upped, with either an r/t or an egrip, just my 2 cents
Don't mean to stick me oar in, but for £150 i suggest you wait and get something like an Ion, but if you're set on Tippmann, the A-5 with reflex trigger and super barrel would be a safe bet.
