If you've tried iTerm in the past, and you've been put off by it's lack of completeness, now is the time to give it another look.

I'd tried using this repeatedly over the past few years, and each time I had come up with the same verdict: promising, but not ready for prime time.

It now has the polish and stability that it needs, and I'm ecstatic to be able to use tabbed browsing once again--for the first time since I switched from Linux. I do miss the line rewrapping that Terminal.app offers on terminal resize, but it's well worth the trade-off to get tabbed terminals, real profile management, plus useful and easy bookmarking.
