yea, I saw a site that offered this, but they wanted to charge you also. I sugest this.
get on winblows
install IE 5.5, Latest Mozilla, Opera 7, and latest Pheonix (from mozilla.org) and look at it from those.
That will cover about 80% of all that is out there. If you have a friend with a Mac or you yourself have one, look at it from there also.
Next install Linux. Go to the command line and type in
linx
www.your_site.com check your site out in a text only browser. Maybe try Konqueror (or however it is spelled) You should be good from there.
