i would suggest saving a while before looking at markers then.
maybe get the rest of your gear first.
1. Mask (save and buy good, deffo worth it)
2. Loader (save and get the best you can buy, so you don't have to replace in future)
3. playing trousers (knee protection = win)
4. pod pack (nxe/cp = win)
5. marker (ion, pmr, epiphany 2nd hand, mini 2nd hand, g3, or even a pirahna pmi if you're desperate. all good starter markers)
6. Air bottle (steely will do you fine, pure energy 48cu 3000psi, most fill stations on punter days don't go above 3000psi)
7. Jersey (thats right last because the rest is more important
)
(if you're only going to attend weekend warriors then you don't have to worry about an air bottle until after you've bought you're marker as we can supply you with one to borrow for the day. same goes for the pod pack but as thats cheaper i can see you getting that first)
