Yes, the Tippmann A-5 is a good starter gun! I've been using one for 10 years now, and still love it. If you like real steel shooting and are right handed, you will love the A-5. With the cyclone feed system, you don't need batteries at all, as you can fire as fast as you can and there will always be a paintball in the gun ready to go! The cyclone puts the hopper off the right side of the gun allowing you a sight line down the top of the gun allowing for easier aiming even when you don't pull it all the way up to your standard shooting stance.
It easily shoots +/-3fps with a few simple modifications (polishing the internals, and using high end o-rings). And with an Apex 2 barrel on it (set at 4 clicks) it shoots flat enough that you can use red dot scopes with it!
With my MonsterSpin barrel on mine (Flatline plus Apex 2) I can shoot out to 125 feet away with a scope and hit what I am aiming at. (as long as I have good paint).
