Best browser compatibility checker

I’m so freakin psyched. I found the best site EVER for taking browser shots. You see……life is not simple, people. A web designer/developer..er cant just create something fabulous and have it look perfectly on all browsers. Thanks to the suckage that is Internet Explorer, we need to be constantly checking to make sure everything is playing nicely. Previously, I was using http://browsershots.org/ which is fine, lots of options there, but your request goes into a queue and results take up to 30 minutes, often not receiving all of the shots you wanted. I usually found myself pestering my friendly Mexican for test shots from his PC. Inevitably, he felt the sting of my frustration, and that made for a sad Mexican.

Fortunately for my little tan friend, I have found Netrenderer… god dammit I love words with double er endings. Netrenderer provides INSTANT screenshots of your site in Internet Explorer 7, 6 or 5.5 on Windows. Lets look at an example, so you all can see what a difference a browser makes;

First, my pretty test site on my MacBook in Firefox:

Next, the same site looking all jagged and stoopid in IE 6 on a PC:

They even have options for mixed and difference overlays, so you can really get a good look at positional differences in IE6 and 7. They take screen shots of the site in both browsers, then lay them on top of each other:

Netrenderer is limited in browser options compared to browsershots.org, but all I really need is access to Internet Explorer on Windows. Thats the only browser I ever have problems with.
I hate you IE
