I think the term you are after is -Duty Cycle, Steps.

I know this sounds a bit..overboard(??) sorta right word.
As I/we have got older, we buy things on a different basis.
Our cash up and down size (well the land size) and get something that doesnt need painting, re building, unless we want to do so.. for next 20yrs.
Sell the vintage cars, 69 camaro, (which also used daily for decades) buy new, no more 'tie rod ends chassis mounts stuff. .. for next 20yrs
... for next 20yrs
Full new
Etc.
We can, scratch together and do now but will not be able in a few yrs time, and apply to the smaller stuff as well like vac pac.Brevelle expresso coffee machine, Leaf blower/vac full on stil
Do our best now not to have stuff wear out/ break down before we move on.
Would like to do same with the boat, but that goes beyond our means. On the other hand it is solid, motor solid low hrs, just the Bimini is getting towards replacing in next couple yrs...maybe this winter?
So current thinking for vac pac is go at least 400w that goes up around and above the $500/$600 Hard to justify a grand or so thu.
