Figured its better to have a guide up than no guide. So this is the scratch pad for what will soon be a bit more featured. I went ahead and posted my excel file that I'm using to do a comparitive.

Your comments are welcome. I'd like to expand this and eventually program it into a web interface so that people who don't have excel can look through the information in a useful way. Maybe even sort by price and certain options they're looking for. That of course is going to take time.
