Id try UKscenario.com mate if you're after an A5. They cover the scenario side of life over there. Ive never owned a BT and im not a huge fan of mil-sim paintball but I bought an A5 when I first got into the sport and it was absolutely bullet proof. They come with the ability to upgrade a massive amount on them as and when you have the cash. Also, with tippmann comes reliability which is a factor if youre going to be chucking your marker around the woods. Or, if you want to go uber cheap, go over to Rap4uk.com and get yourself a tippmann 98 for £40. All kinds of funky stuff you can do to them.
