When I first started playing paint ball before it became mega popular, there were some companies which provided equipment that wasn’t the best. A friend of mine, Jim, once got cut with a substandard clip that had a sharp edge. Once he bought it, he didn’t want to take it back because the shipping alone was more than he wanted to spend, instead he just put on some tape to cover up the edge.
There is a great online site, Ultimate Paintball, which has been in business since 2002. The store in Missouri located not far south of St. Louis. In 2006 they moved into a large warehouse and they order in bulk for very low prices.
I use their web site because they offer a great paintball gun package, ship same day (lightning fast), and there’s a good chance you would get free shipping if you buy enough, and their customer service is great. They also play paintball themselves, and are knowledgeable about the sport, and can help you make decisions if needed.
I know they have several paint ball guns o their site like Tippmann, Spyder, Smart Parts, Dye, Empire, Draxxus paintball gear plus many other brands on their site.
Their top selling guns are Tippmann A-5, (boy would I like another one of those babies), Tippmann 98 Custom, Smart Parts Ion, Spyder Pilot ACS O (I haven’t tried one of these).
