as a matter of fact I just found single mh ballast(icecap electronic) for 125 so that puts it at $250, plus the great deal some one pointed me to last night on the vho(2 110w barebones retro) for $62, that puts the grand total @ $312, add the bulbs, socket and misc, and it will push you up around mid 500's to low six. This is all on very minimal research using all brand new products. I think given a little flexability, and patience patrick can get very close to his goal.
