Globe SP5 costs under $600 new (but is fairly new on the market)
Has #10 nub - don't know if it can use KA attachments for hub. However, Globe does not make their own attachments for the hub, so I think Yes KA will work?
Notice it's recs for capacity: For regular dough ((60% AR) is 5 lbs, for 55% AR is 4 lbs, and ranges for Pizza dough - 3-5 lbs depending on hydration.
