There is a ton of functionality and I actually use two of them for my core routers at my current job. I think for this project they are overkill and there is quite a bit of a learning curve to get them up and running. If you don't plan on deploying anything else, I think that you will find that the tranzeo's are a simpler solution. -- generally - simple radio bridges. you put one to DSL router, and other to computer/switch. that's all.
