I use Opera for that very reason.
Whenever I find a site that doesn't let you veiw it or gives you trouble veiwing it unless you use Netscape or Intenet Explorer, I click File -> Quick Preferences -> Identify as MSIE 5.0 and use that for that particular site(like homestead.com, which works fine in Opera you just have to trick the site), when I'm done with that site I go back to identifying my browser as Opera. I then email the webmaster of said site and hope he/she listens to me, most of the time they don't, but hopefully after enough complaints they will change there evil ways.
