I would not invest $300 in a mixer that small. You'd not be able to do much with it.
Many years ago I got a 4.5 qt. KA as a gift and was disappointed that I couldn't make bread with it, because of it's size and because it didn't include a kneading hook. My current mixer that I've owned since the mid 70's is a 5 qt. lift model (Hobart). It's a good size for most everything. Yes, it has a sizable footprint but, to me, it's worth it. These days I don't use it much because I do my bread mixing in my Zojirushi bread machine which I love.
