I have a PFO 2x 400w pulse start ballast. i bought it used 6months old for 200 bucks.these are great ballasts and more efficient than a probe start ballast.i never got to use it because i didnt realize it took different bulbs and i already had a stash of bulbs and just ended up sticking with my old 175w ballast.
make me an offer!! call or email me.250-215-2596
