i was just ganna buy an el. compressor/tank and then got to thinking this might be a fun project even if it does cost a bit more.  BUT, after looing around i am having problems finding stuff, or finding it for even close to the cost listed.  mostly i just cant get the stuff around here.  but i think i am going to give it a go anyway and just buy stuff on line and suck up the extra $ for shipping.
Q.  will the trackick a/c put out at least as much psi as a sami one?  i would think so.
