Stop in for a cup of coffee

K.. so i'm down to having to order a converter very soon or i will never get this thing together.. anyone here use any of the less expensive options like the ATI streetmaster? or a hughes? Trying not to spend 800+.. was hoping to find a used one local.. but no luck :(
Dad went with one from PTC, which I also plan to get one from, but you are back to $800 ish.
