Alex d is right.Before you think about which gun ,you have to find what you like poppet(Planet Ego,s) spool,(DM Geo Axe).As mentioned go to a walk on, scenario chat to players about their guns and ask to try .Watch the many gun reviews on U Tube. As a general rule the 3 yr old "latest marker " will have all the bells and whistles you ever need. Whereas the budget guns although younger dont always have the same degree of adjustment. I have seen a DM9,going for about your budget and minus a few tweeks it is basically the same gun as the 13. the same is true of the planet guns Ego and Geo series. In the name of fairness All the big name guns with a few years to take them down to your budget will perform more than adequately.Try before you buy is the best advice and bear in mind all the top brand guns can be Techd for free at big scenario,CPPS and Millenium (Campaign) events .
