assuming that you are gonna start torni ball
you could invest in buying an ANGEL LCD for around 250-200 or if you have a few more 'bob' to spend get an ANGEL IR3 for like 300-350
if your just starting,i would get a second hand electro.
angel lcd/ir3, impulse,old shocker,bushmaster,old intimedater ect.
all proven markers expect to pay £150/£350 depending.
if you dont like it you can resell it without loosing to much cash
keep your eye on the classified section mate, theres plenty of people doing some very good deals on second hand guns, and anything else paintball related for that matter
if ur jus startin id reccomend a spyder piranha or summat like tht, they re good guns and most are v.upgradable depends how much u got 2 spend and wether ur serious bout the sport
