As part of your research, you might download the software that the IR Clone uses to customize the MX500 and take a spin through Harmony's site (they've got a test drive option for their web configuration interface). The MX500 can be completely configured without a PC involved, but if you are going to get the IR Clone you could also download the software demo first and see what it looks like.

All three remotes are good products. If you prefer hard buttons (as I do), I think the Harmony and MX500 are both excellent options -- probably the top two choices in the <$300 price range. For me, the MX500's ten-button LCD has allowed me to use the remote to provide full control of a number of devices (including the 950 and a DVD recorder).
