It's now almost impossible to find used c-band dishes in my area also, YET just yesterday, I drove down a dead-end subdivision road 5 miles from my house I hadn't driven down in years just kind of looking, but not really expecting to find anything. Here's what happened:
I'll take "Name that satellite" for $500 please! HELP!
So, they ARE out there, and some are still in almost pristine state! Once you get the "bug" and keep your eyes open, you can find them. I never figured I'd find the exact dish I wanted, and to get it for only $20 (and a lot of removal work). I had been thinking about buying a Tek2000 dish, but I really don't have the money right now, as I just had my roof replaced to the tune of a bit over $8k.
A Tek2000 dish of this sort would be around $500, so it paid well for me to take it all down myself and trailer it home. I got the pole out of the ground this morning, but now am exhausted (it has 300lbs of cement on it, and it's 90 degrees today), so I'm going back tomorrow to get it on the trailer and get it home.
I'd encourage you to not despair over this, and just keep your eyes open. Tell all your friends you are looking for one, maybe even put a "wanted" post in your local Craigslist or Kijiji, and you
will find them. It might not be real soon, but you never know. Hold out for a real good one, don't necessarily take the first one if it's too much work. I'd also never take a fiberglass dish anymore. Spun aluminum, OR mesh. Mesh is better to "hide" or be much less obtrusive if needed in your neighborhood area.
