Pretty much the only advantage to purchasing a receiver is the ability to de-activate and re-activate as need be. I had a divorced customer once who had custody of their child during the summer, and so they wanted to be able to de-activate that receiver during the school year and have it turned back on in the summer (avoiding 9 months of $5 additional receiver fees per year). If it's a receiver you plan to use regularly, leasing is almost always the way to go.
