Help with buying a paintball gun?

Hey I'm thinking of buying a paintball gun and a carbon fiber tank with an electric hopper for around $300 or so. Im thinking of getting the spyder pilot 09 with an eye and a Crossfire 45/4500 Stealth System Carbon Fiber Compressed Air Tank - High Pressure. for the hopper I'm thinking of a Spyder Fasta LED 18v Paintball Loader - Black please answer back and see if i should upgrade anything before i buy. thank you for the answers i appreciate it :D
