I was going to pick up some pis for more locations and it seems finding any 3b/3b+ is tough now. I'd rather not put out a 4 just because it's more money (I know, I'm not spending 3 kagillion extra and I've spent farrrrr more on stupider) and firepower than I need. I do see a place by me that has a few 3a but I'm not familiar with them. does the sw support that model and are there any gotchas? I suspect it is a step below the b (have not confirmed or researched yet) and if the performance overall is going to be annoying may not be worth saving a few pennies. Anyone know or have experience with the 3a with rune?
