Newbie Deciding between suppliers

Hi Everyone,

I am new to this site but I have a problem that I hope some of you might be able to help me with. I have been looking at purchasing new drives but I am in doubt as to which supplier to go with. The ones I have looked at are Danfoss, ABB, Mitsubishi, and Rockwell/Allen-Bradley.

Is there a site where the different drives are benchmarked against one another to see which have the better performance, lifetime expectancy etc.?

I would truly appreciate any advice and information you guys can provide me with.

Thanks
