A year or so back, I tried the most recent model 8-device (with DVR control) Philips remote with my Panny EH85 HDD/DVD recorder, and it contained a Panny code which controlled all the basic buttons.
I know it usually runs about $25,00, but if you could find it cheaper, you could try it. Whether it would control your cable box, I wouldn't know, since I have Dish. But it did control my Dish tuner. The main reason I didn't keep it was because it was extremely difficult to program the learning buttons from some of my other remotes.
But at the same price, I'd go with the Panasonic remote, naturally.
I was considering trying the remote again when I saw that my local Sears had an ES-15 remote-less display model for only $31.00. But it looked a bit beat up, so I decided against it. I should probably go over to Best Buy and check them out for the heck of it. Walmart here still wanted $125.00 for an unopened one.
