These days it really doesn't pay to get anything less than Cat 6 (so you are ready for 1GB) and the prices are really amazing if you shop, so here:

• Amazon.com. As usual this is the benchmark. With Cablematters 5x5 feet at $11 ($2.20 a cable), 5x10 feet for $17 ($3.40 a cable) and 5x14 for $20 ($4 a cable)

• Monoprice is a good place for this kind of stuff as but you have to wait for the sales like the current 15% sitewide. They do have a 2% rebate which isn't much and we've found them very reliable. So they are 1.97 for 10', 2.55 for 14' and $4.10 for 25' so definitely cheaper even before the site wide. • Newegg is also right there at that price point with 10 feet at$1.99 but they do get to $2.30 with shipping, 14 feet at$2.72 and 25 at $4.14 • Staples or Office Depot. With the Chase Ink Plus cards, you get a 5x multiplier for office purchases (so 10% of effectively) plus another 2x so a total of 14% off rom them. The main issue is their pricing is so much higher. More like$6 a cable.
