I would say the exact opposite, if you are going with that db place you may be better off with a local shop. just open the yellow pages and look. There are always little shops that rebuild for local mechanics. maybe go ask a mechanic where a place is by you. I got hosed by dbelectrical and am out shipping money shipping there turd back and forth. I also like local if you have a problem you just go over there and break their windows. I saved money and got a better product by staying local.I say the db. My experience has been good, and for the price you can't beat it. A little more than a dollar per amp ratio.
all test I did on both where done by me then the shop and I did watch rpms voltage and amperage during both tests.
