I have been very pleased with my Quantum L500!
I LOVE the built-in walking foot. Have yet to install the foot pedal....just push the 'go' button and off it goes...at any consistant speed!! Needle up/down is great!
It will get loud IF the bobbin is not in 'right'...or... if there is a build up of 'fuzz' in the (where the top thread runs from the spool to the needle)...old age is making the correct word escape me!
I sew much better with this machine than I ever have---straight lines, even 1/4 in.....
And the distance from the needle to throat is awesome! Lots of room!
I really love it and I got it when it first came out!
If you have any ?????? you may just ask me or Singer has a dedicated # just for HSN customers!!!
