URC offers a line of Lutron dimmers and switches that work seamlessly with their remote controls.
For the remote's themselves I would look at the MX-780 or MX-890 ($250-$500) but make sure to go with an authorized dealer for warranty and to obtain the software (surfremote).
A standard RF base station like the MRF-350 will convert the RF signal to IR and the gear via flashers. If you want more control (video sensors, voltage sensors, triggers, RS-232) then go with the MSC-400. ($150-$400)
The Lutron dimmers specific to URC will always have URC in the model number. If it does not have URC then it will not work with a URC remote. (ex: MRFA-600M-URC-WH) These will run from $120 up unless you find a really good deal.
Not really sure what your budget is but that will put you around $650+ depending on which base station and remote you choose. One thing to note is that the software is not wizard based like Harmony so any activities will need to be made by you the programmer or you could hire a pro. I have used URC products for years and they are tough and extremely reliable once programmed correctly.
To me having a well programmed system really adds to the movie experience and has a very high WAF.
