Awning Conversion - Manual to Electric

I just replaced the fabric on my Dometic A&E 8500 series 20 foot awning. Not too difficult of a job but would have been easier with a helper.....anyway, I have decided that I am going to go ahead and convert it to electric. I know, there are people who live and die by manual awnings, but my parents use the RV as well and the manual awning is a little cumbersome for them.
The downside is that there seems to be limited choices. It's either Dometic or Carefree of Colorado. Anyone have any suggestions as to which brand or model?
My main question is does anyone know the difference in the Carefree Travel'r and Carefree Eclipse awning arms? There is a good price difference but I cant find the functional difference. Also, has anyone had any experience with the Travel'r Steep pitch? I know it's not adjustable, but there is a steal of a price for one on eBay right now.
Thanks for all of your help guys!
