The folks at surchur have improved the interface, so it has a much cleaner design, it loads quickly, there's a 'popular search' option, a 'surchmeter' to see how hot your keywords are with various sources and a nice little dashboard to hold everything. And RSS feeds for your searches, hot topics and so on. No Help option though, and no, the short FAQ doesn't count. Well - I have to moan about something don't I!
All told, it's a nice engine; it does what it should do quickly and effectively. Give it a spin.
