Pneumatic solenoid help

[Cold Fusion]

I swear, finding and purchasing a proper solenoid valve must be harder than buying nuclear weapons. Hopefully someone can help me out here. I am working on a semi automatic pneumatic pellet gun, controlled by a electronic trigger and a fast acting pneumatic solenoid. At least that is the plan in my head. Pressures would be anywhere between 250-500psi. Size is important, as it would need to fit in the stock. Low dwell time between 5ms-20ms is needed. 5v is preferred.

So where do I find an item like this?

But on the serious side, Look through the parker site and get a idea what their part numbers are and then keep ckecking eBay.
