Thanks, cheap is a relative word, I can buy a new weber for $289.00 $aus.
I can buy second hand ones for a lot less, but if I did they would require work to undo years of people fiddling & possibly a rebuild . the bargain used ,becomes not such a bargain.
New Stromberg downdrafts are advertised here in Australia as $600 each!
Reconditioned often for the price of the webers. & I believe Webers would be better than Strombergs. Used Strombergs are common but all at best would need stripping to match jets etc, & all ,by now ,for decent performance would need the butterfly shafts rebushed adding more cost.
