Works for me
All I have to use is a Spyder Victor II with standard internals and bolt but a 32Degree LCD trigger set to 12 bps so it doesn't chop, a 14" J+J barrel, a Reloader II hopper and a 3000psi C5 air bottle. Cost around the £160 -£180 set up and ready to play. For and extra £50-£70 I can upgrade to an Apex and get that flatline a effect for the range, but why spoil an already sound setup when I can spend the extra on paint.
It's the bloody ugliest thing I've used, but drops the balls very predictably, and at 12 balls a second without chopping, and I can spray and pray on a budget without paying loads out on an expensive marker setup that only gets a days play every few months.
