I started out with a Spyder E-99 and I loved it. It is very durable and requires little matienence (sp?). You'll love this gun and kick some major ass with it.
The first thing I would recommend when getting a E-99 is a electronic hopper, and then get a new barrel.
Any barrel would really be good. I used a DYE Boomstick, but thats expensive. So you could use a SP All American Barrel (

But please take my advice, do not upgrade this gun too much. You will regret it when you want to get a better gun. Save your money and use this gun for the learning expierence.
