domain Repairing.biz plus category related .com's

[lcapece]

Actually picked repairing.biz up on a drop last week, I know BIZ is pretty much the bottom of the dung heap, but what any ideas as to it's undeveloped value?

Also have a cool "three way" .com set - looking to get in idea on monetizing or opinion on value:

MP3PlayerRepairs.com
LcdTvRepairs.com
PlasmaTvRepairs.com

Many Thanks!
