I have a firend who absolutely loves her 27,¨ and uses it every chance she gets. In comparison with my 201 she sais it feels a bit sturder and more solid. I have to say my 201 is on the solid side, but I think I will agree with her. You will get used to manual thread release (a lobe on the tensioner). A long bobbin hold less thread than we are used to with round bobbins, but she has found new replacement bobbins on the web and she winds a few in advance for every job. In the beginning you will not mind winding bobbins at all :- )
I have another firend who swears her 28 does the best stop stitching and behaves very well with the buttonholder. I assume a 27 is up to the same standard. She has several vintage machines, and has this 28 dedicated to some types of jobs along side a 201.
I'm afraid I haven't owned one my self, but I have noticed the fancy decals and the vibrating shuttle mechanism.
