AJA io -or- PMW-EX30 dilemma.

Do I buy:

  A 17″ laptop ($3,000), eSATA ExpressCard adaptor ($100),
external hard drives ($400), and an AJA ioHD ($2,800) to record
a live switch 1920x1080i60 SDI feed to ProRes 422…

or

A Sony PMW-EX30 XDCAM EX deck ($4,000) to record
a 30 Mbps 1920x1080i60 VBR stream to flash media?
