I looked into Combi over some time ago.
built in models then were a bit small for use , and
then there was that added installation expense
as I understand it , the Anova counter top model is a decent sie
and no additional expense for instalation
you do need dedicated counter top space
and it seems the Anova has had several glitches
( possibly now fixed ) over the course of its y0ung life.
and the price as all prices these days
had certainly gone up considerably.
