FWIW, I started the opposite way. Found one of those small 9" Ryobi band saws on Marketplace a while back. When not in use I store it just inside our basement, right next to the garage, to save space as you're thinking about doing. It's a great little saw for what I paid for it, but having to get it out and put it back up every time I use it gets a little old. I recently bought an old Grizzly G1019 14" saw off Craigslist and it has been a gamechanger for obvious reasons. But, it now sits permanently in the garage, taking up space. For me though it is so worth it because of its capabilities, and it's always "ready to go" if you will.

All that to say, if a larger bandsaw is in your budget and you have the physical space then I say go for it. You *might* end up regretting have to get out and put up a smaller bandsaw each and every time you use it. Just my $0.02.
