For no price range at all electronic guns are good choices because they are reliable, easy to use and fairly easy to take care of. An angel is probably the easiest to take care of, but you have to decide if you really want to pay all that money as a newbie. Impulses are also fairly easy to just go out and play with, not very difficult to set up, and really reliable. The maintenance will be a bit more involved though. Basically any gun can make a good newbie marker if you're willing to take the time to learn how to clean and lube it.
