Canon 50D Wireless Remote Control Recommendation?

[bunnn]

So I've been using the self timer on a tripod, and it's gotten to a point where I don't want to do it anymore. I've looked around for a good wireless remote, I've seen a few but there's no solid reviews on them, especially for the 50D. I'd like something that can last a longer period of time and compatible with FF bodies later on. Thanks in advance for any recommendations.
