We have the current equivalent of that old Summit.
The E-470. Absolutely love it.
https://thd.co/2IjtgfyIt's a bit more than $300-$400 though.
Going into its third Summer and we have replaced nothing.
Although it needs a new light switch for the knobs.
VERY heavily used.
Even if we're just using the kettles it's pressed into service
as a warming/holding oven and steam table.
Only regret is that we maybe should have chosen the E-670
for it's larger capacity.
