ONEAC CP 1107 Power conditioner

does anyone out there have any information on this unit. Is it worth using for a system. have a chance to buy one, is it worth it.
IIRC, it's rated for ~6 amps, leave about 30% for "head room" which leaves you with 4 usable amps, enough for about everything except your amplifier(s). My old rule was to not spend more that $10 per the unit code (7) when bidding for them on E-bay.... Very decent basic power conditioners, especially if you add a few (1.0, .1 and .01Uf) poly caps across the lines AFTER the fuse!
