storage

I have a limited budget and am just a hobbyist, so need to keep costs pretty well contained. I have an M1 MBA, but want to move to a Mini. I've got about $1K to spend. I can get a refurb M1 mini with 1TB SDD and 16GB RAM or I can get a new M2 mini with 500GB SDD and 16GB RAM My MBA 500GB...
