What PHP accelerator works well with PHP?

I know that the Zend Accelerator works well, but it’s expensive. Turke MMCache is the best freeware PHP accelerator for PHP4, but has some problems with PHP5. Any thoughts?
        
Best Freeware Available, I think, is E Accelerator (this site uses this with PHP5):

Best Payware, Zend:

Couple others:
– PHP Accelerator (http://www.php-accelerator.co.uk/)
– Alternative PHP Cache (http://pecl.php.net/package/APC)
– AfterBurner Cache (http://bwcache.bware.it/)
