I think it runs about $5000.00 initially and about $1000.00/yr after that .
I recall $3K upfront - and it’s no more than $100 a year to maintain. We stored our first of two child’s CB. We figured if the second child, or even a parent needed it, there it is.
I expected we’d hear more of this kind of success by now. But any success is good progress. I hope this type of research continues and more people store CB. It’s really easy.
