Howa 1500 SA vs MINI for 223 build

[264win]

I’m thinking of doing a switch barrel 223 /300 bo on a howa, but torn between the standard S/A and the mini.
Has anyone else been down this road ?

I know they stopped making the SA in 223 and switched over to the mini but that being said the mini doesn’t seem to have the aftermarket support the SA does. Now I don’t know if that’s a big deal or not for you but personally I’d like to be able to get magazines from more then two companies and chassis/stock options.
