Yet another purchase advice post...!

Hi all! Like the title says, I'm asking y'all about an upcoming purchase. I'm a new homeowner and the repairs, replacements and projects are piling up. Like cutting into drywall for shower valve replacement and cutting sheetrock to complete the fire safety partition between the house and the attached garage; cutting tile; vacuuming up leaves and debris from around the pool deck; vacuuming leaves out of the gutters until I can install gutter guards; and so on.

I have read plenty of positive raves for the M12 FUEL Oscillating Multi Tool, and the M12 FUEL Packout Vacuum would be a great fit for my existing Packout boxes. But would I be better served getting the M18 FUEL versions of both instead? I love the idea of vacuuming around the yard without worrying about where I can plug in my Shop Vac.

I thank you all in advance for any advice you can offer!
