Since me - like Zep - use IE for work (even at home in this case) I take a chance just using IE7 at home (and as for the others - can't touch them without a mess) where I have IE6 and 7 at work.
I'll wait until IE8 becomes much more stable before I even try that experiment (I just spent 50 hours since Friday doing major systems upgrades just to get the systems to work with IE7 decently...)
