OS X Browsers (Score 1)

I guess my issue is this: I don't like Netscape because its flipping huge, and seems slow to launch, and generally slow. I haven't used Mozilla much -- I'm on a dial-up connection, and I don't have time to keep downloading the new version that comes out every three days. I've tried Opera, and I liked it -- up until they threw in the tabs. Opera does not appear to have a keystroke for changing tabs -- that I've found. IE may not be ideal, it may not be up to standards, it may be evil, and all that. But, for me, it works. I'd love to be using some other browser, but I have yet to find one that is fast, stable, has keystroke shortcuts, holds to the standards, etc.
Please give me something other than IE --now. I'm sure Chimera will be there eventually, but I'm somewhat conservative. I want one browser. Not three. Not one that gets reprogrammed every week.
Can any browser meet those requirements?
