Well im also a noob so to speak. Ive been playing about a month now, and like you i had a lot of trouble deciding which gun to buy.
After asking all my friends both online and off what they though, and doing some of my own research (
www.pbreview.com is an awesome place to go) i bought a Spyder E99 (125 bucks at actionvillage.com). The spyder is awesome. Its very easy to clean and maintain, the gun is sweet (shoots 13 bps, and until you get more practice you wont be able to shoot 13 bps on semi auto). Only thing i recommend is buying a new barrel, i got the Smart Parts All American 2002, and in my opinion its comparable to the Dye Boomstick (not to mention the AA 2002 is also about 30 bucks cheaper).
If you want a gun that you can do a whole buncha crap too then i would recommend the Tippmann 98 custom. It is similar to the Spyder in its ease of upkeep and maintance, but you can customize the crap outta it. Personally i only chose the Spyder cause i thought it looked better, and the only customization ill be doing is when i buy a new gun to replace the spyder.
Ohh and the electronic hopper is a good buy, i got the Evlution 2 for about 65 bucks from paintballgateway.com and even fully auto with the spyder i cant outshoot it.
overall with the gun, barrel, electronic hopper, jt nvader thermal mask, and 20 oz anti siphon tank i spent about 350 or so (not including shipping and handling, overall i spent about 400. shipping to hawaii sucks, but its still cheaper than the stores out here, they wanted 200 for the spyder ONLY!!)
Best advice i think anyone can give is to tell someone not what gun to get, but what benefits they personally experience with their own set up. So i would advise you to do the same, check out the reviews, ask your friends and even the guys at the pb field you play with. in my experience those guys are very friendly and always willing to help out a new paintballer.
