I decided on Steelcraft because they are made in the USA (Corona CA) and I called and spoke to them myself and they provide great service. Plus I think they have the best look of all the ones I looked at, including the Mopar Side Steps.
As for installation, I had my local body shop put them on for $100. I live in a condo and have no place to really do this work myself, but it does not seem to difficult if you have access to a garage and tools. I did watch them do the install and having a lift makes it much easier. Plus they were able to use multiple jacks to really level the bars to where I wanted them(they put a jack under each bracket and use them to get the bars right where I asked and then used there air tools to tighten everything.
