The Xsight Touch or Nevo C3 is about equivalent to the 890. There are still a few on ebay for $200-$300. I have about a dozen of them, most of which I bought for $30, before the supply dried up. Excellent remotes if you use Remote Master, but probably not quite as durable as your old 890 (my buttons started to wear out after about 4 years).

You could save a lot of money if you simply used an IR remote and IR repeater instead of RF. It would accomplish about the same thing. I imagine you have to aim at your TV anyway, so putting in IR receiver nearby would be the only difference. In that case, a repeater is about $15 and a Nevo C2 is about $20, again having about the same capabilities as your 890 aside from RF.
