now, out of the markers listed, i would go with the rsx. it's an ok gun, nothing special. for the same price you could go with [link=http://www.actionvillage.com/AVI-Paintball/paintball-paintball-guns-redz-paintball-guns]this[/link], for those of you who play paint ball...i know it's an ion, but it's the reds one with a few more creature comforts. should beat out a spyder. i would say just save up an exra $100 and buy a [link=http://www.actionvillage.com/AVI-Paintball/paintball-paintball-guns-dangerous-power-paintball-guns]G3[/link], it is a tournament lever marker for 300 bucks, multiple modes, flip asa, clamping neck, 14 in barrel, and will beat the brakes off of a spyder and ion. here's mine.
