In for a penny in for a pound. I would really try to talk someone out of a 6 foot dish as they are going to be disappointed especially if they are spending the money to buy all new equipment. That is a lot to spend for very little reward.
If he absolutely has no room for a larger dish or because of covenants I would look for used gear. If he absolutely wants new and cant hand a larger dish then Tek2000 is the way to go. Just be sure he realizes he is spending a good chunk of change and a lot of effort to set it up for little reward.
I’m glad I went with a 10 foot instead of an 8 and my only regret is that I didn’t have room for a 12 foot dish.
