I picked up 5 of the 1k+ domains from LBrown for $9 each, and here's what I got:
All .net
All had US searches = to the global (I got lucky

)
KW1: 1300 search | .90 CPC
KW2: 1000 search | .86 CPC
KW3: 1900 search | .90 CPC
KW4: 1900 search | 2.32 CPC
KW5: 1600 search | 4.18 CPC
Not that the CPC matters because I plan on selling products on these.
Additionally, I purchased several higher-search US KWs for negotated prices (all .orgs). I'm not going to share the stats there, but I'll just say they were quite good.
All 9 these keywords are good product-related buying words that could sell products on amazon or, in most cases, from other affiliate vendors for even higher commissions.
LBrown's customer service is fantastic and she quickly responded to my numerous PMs/emails until we had everything worked out. The keywords are great, product focused if you don't want to worry about AdSense, and have matching aged domains to boot for a good price.
Great service, very much recommended.
