i have a Sony RM-AV3000. you can find a review of it here:

if you do a search, you can easily find one online for less than $80.
and i promise, it's the last remote you'll ever need. it has hundreds of presets and can "learn" from other remotes. it took me about a half hour to customize it and it's been flawless ever since. trust me, you'll be happy you spent a little extra money now rather than having to buy multiple replacements for cheaper universal remotes later on.
