no problem...I suggest buying new instead of used if you are concerned about possible breakdowns...Just a quick FYI the new AC 70's are exactly the same as the 300's in fact there is no difference at all...good luck on your search...sorry dean..im looking for something from the newer line of aquaclear but thanks for the heads up!!!. I had a 300 on there and it bit the dust for some reason..so therefor im still lookin...
