I received the Brother 1034D 3/4 Thread Serger with Differential Feed as a Christmas gift many years ago now, and I still use it today. This is a beast, a workhorse of a serger and don’t let the plastic exterior fool you, it isn’t some cheap piece of crap. I’ve used it on denim, faux fur, you name it and it works like a champ. I’ve been bad and never had it serviced, the only problem I’ve ever had is the belt squeak at full speed, but to be fair that is five or more years of use in an environment that has dust like lunar regolith.
What else can I say, this is the best home serger you can get for the money, and the price isn’t going to bankrupt you.
