Unfortunately today for the casual hobbiest on a budget it's either going to be sourcing a local dish that is not being used anymore or Tek2000. Yes, I know there are a variety of fixed az/el mount dishes for those interested in a single satellite that you can buy off of ebay and other places but for most of us if you want a polar mount and an actuator to go from satellite to satellite that is the case.
Tek's dishes are sourced from China as are most of the ones available new today except for commercial quality dishes. I'm 'satisfied' with my dish but then again you do pretty much get what you pay for. With careful installation and paying attention to detail it should last quite awhile but it's not the heavy duty beast's of yesteryear unless you want to pony up a few thousand dollars or more for one of the domestic made ones. It is what it is.
