Unfortunately LLLL.com prices seem to be coming back down quite a bit, but finding a good acronym (especially if its a memorable or well known one) will help.
- pbyw.com mid $xx
- rmpq.com mid $xx
- gfnk.com (G-Funk?) - mid to high $xx
- lhje.com - mid $xx
TM's appraisals sound about right to me, try going for pronounceables, they hold the most value and will be easier to sell, I think the unpronounceable LLLL.coms like qkzl will loose a lot of their value and people are gunna get hurt
