The Spyder I have the Stab on was $10 as well. Apparently it was "broken" but just needed new o-rings.
I put a $25 SP Progressive barrel on it and a $80 used Stab. But I understand not wanting to spend that much. A guy I know at the local field was selling it almost brand new and the price was right, so I picked it up.
The venturi part was hard to remove. Otter SC Customs showed to use a long thin pair of needle-nose pliers, but I had none that would work. So I used 2 nails held tight in a pair of vice-grip pliers to twist it out. Still took a lot of force. It was in there pretty good, with a bit of loc-tite I think. You might want to try some heat on it to loosen it up.
Obviously polishing the internals is a cheap and effect way to lower your pressure a bit. The issue I have with lowering pressure right now is getting the FPS up. My Spyder will recock to as low as 300 psi, but it needs 500 psi to shoot at 275. I have an extra valve and valve stem, so I might try working on them a bit.
