buying a marker is a lot like buying a car. When you just ask what to buy nobody is going to be able to help you. It would help if we knew a price range, if you want new or can settle for used and what type of paintball you will be playing. Help us help you
Well what guns are you considering? I would recommend buying used though you would save some money but make sure that it is from someone with high feedback
For electric markers, my fav starter gun is the Proto Rail. Mechanical, a 98c or an a5 are great choices. If you want a nice looking military style gun, the Alpha Black ( essentially a 98c) is another excellent choice.
