Spotted these solenoids on eBay. 24v, rated to 1000psi and only $15. Don't know if anybody is interested, but thought I would share. http://www.ebay.com/itm/PARKER-SKIN...27-/161266682725?_trksid=p2141725.m3641.l6368
Solenoids are pretty easy to rewind if you want to run a different voltage. The 1/16" orifice on the other hand isn't worth it.
