Unless you absolutely have to have that $70k SPF, look around - there are a
lot out there for around $50k that are debugged and broken in. If you haven't
had one of these before you would not be risking a major financial loss on the
$50k version vs the $70k one if, for whatever reason, you weren't happy with
it. There are some great stories here where people weren't really up to a Cobra and took a bath when they got rid of it. Not saying you are like that or
anything but just putting it out there for consideration.
Good luck with your choice! Whatever it is - if she is happy too, no problem.
