There's always this dude from WGL Design:

A bit pricey, but doesn't require a Homeautomation package.

P.s. I have 0 experience with that product. I DO use the W800 made by WGL. However, it interfaces to Homeseer...which does my X10 RF to UPB translation.
Thanks for the inputs. I visited that site, it says:
"These signals are received by a quarter wave whip antenna and presented to a very sensitive 310Mhz receiver internal to the UPB572 module. This data is then mapped to specified UPB addresses, Link ID, Direct ID and Network ID. "
From reading, it seems the UPB transmitter using 310Mhz ASK RF transmitter. Some of them using 433.92Mhz ASK transmitter, those transmitter can be purchased on eBay for $7 or so. Could some software interface with those transmitter directly to make a device like X10 palm remote?
I am currently using X10 and love the X10 palm remote. People tell me UPB is better, so that I am trying to look into how UPB can make things better for me. One thing I don't want to give up is the handhold remote....
UPB runs over the powerline, in an RF protocol. All that box does, is allow you to receive the X10 RF from your Palmpad, then IT maps THAT to the UPB ON/OFF/DIM/Link. You tell it WHAT you want mapped to what (A3 = UPB Dining Room Light, or A4 = UPB Dining Room Link). You use Upstart to setup the links and switches, then somehow load that into this box.
After you do that, you push A3, it is received by this box, which then tells the UPB PIM (Powerline Interface) what UPB commands to send.
You don't lose anything, but gain UPB. Or, as has been pointed out, use something like Homeseer, which can Rx and Tx X10, UPB, Zwave, etc..etc... BUT then you need to run a computer 24x7.

Thanks, Dan. I don't want to run a computer 24x7. From what you said, UPB does not have its own RF remote control like X10?
