They look great for the price!
OOPS... my mistake. I left off a digit when looking up the numbers. Quiltingnan (above) is right... The 127s are the smaller versions of the 27's.
The 127 and 27 are the same machine, the difference is where the bobbin winder is. 127 its up higher, 27 its lower.
The 128/28 is the smaller version of the 127/27.
