Don't misunderstand us, there are benefits in buying a cheap two tone gun (when starting out), we can't know where you will play but its entirely possible you'll spend £100 on rental over your first 4-5 games. Owning a two-tone £100-£160 gun could work out better for you.
Given the way I entered the sport (hire purchase TM Glock 17) I would say that getting your own rifle class gun instead of hiring can work out, I got that RIF through wolf armouries which plays at a very small paintball venue (10 minutes away from me) where I was not disadvantaged by having only a sidearm - but I had to play the UKARA criteria before I could take it home.
I think I spent £115 on the gun and £80 on a pair of extra magazines and a double magazine holster and pistol holster for my belt + some gas and BBs. I would have been better off with a G&G M4 - and tbh I knew that but wolf don't stock G&G.
So don't misunderstand us, you don't have to hire, but if you're going to start out buying a (two-tone) you want to go with something cheap (cyma/G&G/ICS) or something with a solid reputation in the £300 range - to me that's the ASG scorpion or a Krytac M4. But putting either through two-tone is crazy to me.
Given that you've not played airsoft you definitely do not want to be buying a [heavy] VFC gun.
