friar,
You can pick up an io on flea bay for about $200. Purchasing from CC, assuming you can get one reasonably fast, will cost about the same, with a mandatory three month service contract.
I have modded several versions and have not seen a difference in the video quality from one unit to another.
If you go the badflash bios chip replacement route (vs. qnx flash), one version is generally as good as another.
