Query: Twice dissapointed

The GH1000 appeared to be the best bargain in the search. A $170 trimer for $69 plus shipping. Upon receiving the product and the minor assembly required, it was plugged in and ready to go. For almost two minutes it worked perfectly...then nothing.The GH1000 was exchanged through Amazon.com and the second one arrived within a week. This one wouldn't even start. I checked the cord by plugging in another tool, and the second tool worked fine. So, the GH1000 was returned for a refund. But that's not the end of the review.Still needing a trimmer, I rechecked the retail stores and their web sites for prices. Four different stores had the same product, same price ($69) and no shipping. Guess which one I didn't purchase.
