Hey welcome to the forum! That new receiver is something a lot of us are waiting for, and I think it's due out next month or so.
You don't mention what kind of tv you're interested in, so I'm assuming you just want FREE tv , like me and aren't too particular.
I can find more than I ever want to watch with a 4yr old box now, but to really enjoy fta you need an HDTV and a receiver that does it.
Most of us say start with at least a 1m dish for reliable operation, should work fine for you in FL. Dish, motor, cable , reciever and some patience is all you need. You can buy dishes from some of the sponsors listed at top of the pages here. Some of us like to scrounge used dishes, especially the old Primestar tv sat-dishes, they can still be found ifyou look around enough. There sturdy, mostly well made and the lnbf on them will still work in most cases. Or the old Direcway/DirecPC satellite-internet dishes , also work but are usually smaller somewhat, than the primestar dishes. Shipping on anything bigger than about `1meter can get crazy these days. Check the sponsors >you might find a package deal to start out with that won't break the bank.
Post any questions about particular items before you buy, we like to help folks here.
