Opera Mini 4.2 beta is the first third-party browser for Android. Although it's just a beta version it looks pretty good. Cnet took the new browser through its paces and it came out pretty well. They did have a problem getting the video playback feature to work but that will surely be worked out by the time it comes out of beta.

"What's distinctive and commendable of the Android-optimized build: fast speeds over T-Mobile's 3G network, a very crisp display, and quality that approaches the iPhone when it comes to viewing a zoomed-out Web page, thanks to both screen size and image clarity. The G1's two menu keys also enhance the experience, making Opera Mini's controls easy to access and navigate."
