Transfering analog mixes to digital - converter options

[mikoo69]

I was going to purchase a BLA Sparrow to transfer 1/4" analog mixes to digital. However, a friend has a Digi 192 ProTools HD rig that he will let me use. Is there any point to getting the BLA or another high quality 2 channel A/D, or will the Digi 192 do the trick? Would there be a benefit to the Sparrow or another high quality 2 channel converter?

In general, when looking at converters, are 2 channel converters in the $1000-$2000 range vastly superior to 8 or 16 channel converters in the same price range? I ask because I definitely need 2 channels of conversion for the project I am working on currently, though there are instances in the future where I could see myself wanting 8 or even 16 channels of A/D D/A so I'd like to know more about this before I buy anything.
