I loved my lightweight Brother purchased at Walmart for classes and a back up---unfortunately I gave it to my DIL with gift card for classes at JoAnne's (she does not live nearby) to encourage her to get the sewing bug--she definitely does NOT have it.
Regarding your squeak--can you locate where it is? Reason I ask is the foot pedal of my really nice and loved Elna squeaks sometimes--the place where I take for maintanence doesn't work on the foot pedal but told me to open the plastic case and make sure no lint/dust--just haven't taken time to do that.
