I buy my hard drives when they go on deep discount sale. Bought my last two, Maxtor 250 giggers from Circuit City for $59.95 each, after waiting for the rebates to come in.
So a repair shop getting my old drives is not an issue for me.
Today the drives usually come with a one year warranty and I've only once in 30 years had to use the warranty, anyway.
What I learned from this article, however, is this:
$59.95, $69.95, even $79.95 is cheap insurance to safeguard my data. If my hard drive on warranty should go down, I'll TRASH it instead of sending it in for warranty repair.
Good article.
