I am looking for a marker for my Dad. He does not care how fast it shoots or what it looks like, the only thing he wants is for it to shoot paint and be as cheap as possible. It can be an ex-rental gun or and old marker it does not matter as long as it works. Also if you have a co2 tank and/or hopper (can be a gravity feed) that would be great. Let me know what you guys have! Thanks.
