you are absolutely right, i got my 1500v.3 for 340. i was not trying to be difficult, just stating fact. i hope you can find what you are looking for.Dbr has a sundown 1500d v.2 for under $350. So finding a v.1 for under 300 isn't that hard
audiopipe gd-6001 or the db drive pd2000I've tried it. They will protect at 16.0v
