Ouch it will be hard to do for your budget. On ebay and caigs list people really think that gear goes up in value over time. I had trouble getting my cousins 98's mask and tanks for under $125 each. You might get lucky though, plus we are here to help! Personally I'd stay away from spyders though. That metric gas line on them just ruins them. You might want to look into bt 4s, just a thought, I know kee does rental packages with them, but have no idea what they are asking, it might not be cost effective.
