We bought and installed a Shaw System from Ajijic Electronics in 2012. In 2015, they bought the system back from me. Mike Merryman is a good guy with whom to do business. My point being that they also probably have used systems to purchase as well.
Originally, I brought down a Shaw System from Canada for our house in San Pancho. Yes, even the elliptical dish fit in a large suitcase... well padded with towels. So it is possible.
Do the local thing. When your dish gets blown out of alignment or something else, they are an easy phone call away and a short trip for service.
