Don't spend a lot of money on an Angel. (One of the best guns.) Spend a reasonable amount and get a semi-good gun. Around 50-150 dollars. My friend invited me to his house and challenged me to a match, I had a pathetic blade by brass eagle. He had an Angel with nitrogen, also, he had tournament grade paintballs, the Anarchy set. I had Wal-Mart. I won. Get a good gun and practice.
The blade.
