Ok so as I posted before I was going to get the Mercury II receiver. But after doing a ton more homework alot of the feeds I will be looking for have to do with motorsports and looks like most are HD. What receiver would you all recommend? I have been looking around and know that cheaper doesn't ever mean better so I thought I had better ask. Does anyone have experience with the Captain 8000 HD? Here's the link. I notice that most all the other HD receivers are $400+. I really need to stay around $300 or less.
