I'm going to begin the evaluation process for a new power chair. Assuming I stay with Permobil, Medicare as my insurance, it looks like the options will be the F3, F5 or the M300. Does anybody have any opinions on any of these models? The mid-wheel seems like it is a bit more compact and maneuverable. I don't think I'll get it but does Medicare pay for the standing version, the F5VS?

I don't plan on using the Permobil back, the plan on using one of the three available aftermarket backs.

Thank you.
