Thermaltake BlacX Duet (ST0014U) 2.5" & 3.5" Black USB2.0 & eSATA Dual Hard Drives Docking Station 41.99$ + tax or 30.99$ with BTEJJHB59 code[YMMV] A/R,

I just got this unit before the holiday, with a similar deal, maybe ~$31 after rebate and NE code. I love it, should have bought one a long time ago. At $30 it's a steal, people sell the single ones for that, new and used on CL and e-auction. The only thing lacking is a killer app to clone drives from within Windows, and maybe it's out there and I've just not discovered it yet. The stuff I've used so far has not made the clones 100% so a repair boot was needed to finalize. But overall, a great find OP!
