Another great source for component cable (if you want good cable) is bluejeanscable.com. I was very skeptical at first that I would notice any difference in cheap vs. mid-priced cables, but the component cables from bluejeanscable.com really did make a great difference on my DirecTV component connection.
Ebay also has some cheap deals on DVI cables. Apparently with DVI (check other posts on avsforum), the cable quality on any length of cable under 10m or so really makes no difference. I can only say that my 3m cable from eBay for $10 does everything I need it to. I compared it to a $70 DVI cable from Best Buy and noticed no difference, whereas I noticed a huge different between BestBuy component cable and BlueJeans cable (bluejeans being much much better)....
My 2 cents on cables.
