So I have been on an Amazon.com kick as of late. In the past couple of months I have been able to pick up some good Christian rock at pretty decent prices. I usually buy the used ones that are real cheap (aside from the standard 2.98 s & H) charge. Some of what I have found are:

Fighting Instinct-s/t features T J Harris of Decyfer Down
Re:Zound-Re:Worship- perhaps the best worship album I have ever heard
Old Man Shattered-End of the Matter and The Other Side of Fear
Candlefuse-Never Go Unheard
Mylon & Broken Heart-Crack the Sky
Idle Cure-S/t & Tough Love
Life of Riley-Days Away from Life, this was a great cd,wow blew me away
D & K-Streetlight & The Pledge
Wyrick-Mental Floss, reacquired after losing it.

These were all realativley cheap. Man I love Amazon

Me too. They're helping me get back into Rush, among others.

I have been using Amazon.com for the last several months as well, but not to buy used cds. The last 5 to 7 albums I bought have all been digital downloads (from Amazon). I haven't paid more than $9 for a single one of them (usually less). Best part is no s&h, and no waiting for the mail.
