OT: data recovery - bad blocks on AIT3 tapes

[Jacob Yocom-Piatt]

have 2 sony SDX3-100C AIT3 100 GB tapes here that have bad blocks and 
will not read in our tape changer. i may need to get these sent to a 
data recovery shop, but would prefer not to be viciously reamed w.r.t. 
the cost.

any suggestions on good data recovery places in the US?
cheers,
jake
