SP-1 is a great first marker! I would recommend getting a cheap steel compressed air tank instead of Co2 if you can afford the $50-60 for it due to it not being prone to freezing up on ya' on cold days or shooting downhill with Co2. The SP1 can be safely used with Co2 but it's better to get a anti-syphen (sp?) kit for it installed. By the time you do all of that you can get a cheap steel air tank (48/3000) for the same money. Check out some of the ebay stores for some good deals on tanks. I saw a starter setup with a SP1, 50/3000 tank, mask and a motorized hopper (plus pods, etc) for around $250ish. The prices and combos always change but there are some good deals out there unless you have a local pro-shop to go and get your equipment from. I always recommend getting stuff from a local store due to service after the sale, etc. Keep the money local to support your store near you and keep them open.
Good luck and have fun!
Let me know how you like it when you get it. I'm thinking about one myself. Just PM me or something...
