Oh, don't beat yourself up over this. $300 is a lot of money and you
made the *right* decision. Maybe it turned out wrong, but you couldn't
expect it. $billions are spent on 'net purchases and mostly it works
out. I bought my welder on the net and if it had been bad I don't think
that I would have regretted the purchase. Yours was just bad luck, not
a bad decision.
