I recently bought a bunch of cables and other audio stuff from monoprice.com. Their prices were low enough that I was worried that the quality might suck, but I'm really happy with the quality. Hopefully this will help save someone some cash.

Thanks frenchy. I ordered some HDMI cables and some audio cables. Yeah, it's decent stuff at a great price. Some of it is great stuff. I'm a bit wary of their very cheapest cables. IMHO, you want to get the heaviest gauge you can...

Would they have best guitar cables. Does quality of guitar cable really make much difference? I see in music stores a big range of cables.

 I found this place in Madison WI. They have great prices on all kinds of audio hardware. It seems they buy bulk from stores that are closing and offer the products at significant discounts. I just bought an audio-technica lapel/guitar mic for less than half of list. I was the real deal and works fine. Give them a look you'll be surprised.

I bought some cableage from firefold.com. Not bad. I totally dig newegg.com for computer gear.
