I picked up the TrakPower TK-950 awhile back from Tower as an open box. I think it was around $45. It was brand new, did not even have the stickers on it, tips never used. I have only used it a handful of times so far, but am very pleases with the product.

As for your issues with the TK60, sorry you are having a problem. I have heard that TrakPower stands behind their product and am sure they would take care of you. Tower I am sure would take care of you as well, I have had good customer service after having issues in the past before, and they were quick to resolve them.

2 options, get credit from tower, or replacement from either. would not hurt to have a decent portable just to keep in your pit bag.

Either way, I would notify TrakPower and let them know the issue. One way a company can fix issues with their product is feedback, both positive and negative. If it is a known issue they may have resolved it with new stock.
