Data Recovery companies

has anybody here ever used a data recovery service? if so, which one did you use, and how much did it cost? i've currently got 2 drives (1 desktop, 1 laptop), that i would like to get the stuff from (music, pics, older software, e-mails, etc.). i know the desktop one isn't recognized by the computer at all, i've tried a couple of things. however the laptop one, i'm not totally convinced yet. anyway, i was wondering if anyone has heard of this company. - sos
