Mods to Transports/MSB Link

I'm looking for a transport to use with a MSB Link 3. There appear to be numerous individuals who modify DVDs; has anyone compared them or do they all do the same mods?

Same question regarding my MSB. I'd like to make an informed choice. Thanks in advance.
Contact MSB, their MSB Link output board is in production (according to my local MSB dealer). The board can be attached to nearly any DVD/CD player and the digital output will be reclocked and upsampled. It's designed to eliminate the transport from the sonic equation. I believe the price is $595. I have no personal experience, but the product looks promising.
