Last month I mentioned that you shouldn't overpay for HDMI cables: The cheap ones are generally just as good as their pricey counterparts. Of course, the best deal is when you don't pay anything at all, like with eCost's free-after-rebate Azio 6-foot HDMI cable.
Shipping is way overpriced at $9.50 (for a cable? C'mon, eCost), but in the end you're getting an HDMI cable for $9.50--a great deal any way you slice it.
The rebate offer (PDF) is good until June 30, though who knows how long eCost's stock will last? For what it's worth, I just picked up an Azio USB/SATA hard-drive enclosure--also free after rebate (same form)--and it's working like a champ.
