Check out their website. They are up to DX3 now, which is their one-box solution but they also have some new options in their highest-level "X" line, being the CX and EX. You need to read closely but there are distinct advantages related to each model and you can use both (one as server and one as renderer) for a very high level solution. They are great about upgrading existing models and I just made the decision last week to go ahead with the Gen 3 upgrade for my DX. To your question, I have not yet seen any reviews of the new'ish DX Gen3 but I know some are using it. The Gen3 is supposed to offer meaningful upgrades to Gen2 so if you are interested in the DX I would go for the Gen3 but you should first read about the CX and EX.
