I have an Emerald 183 I've had for several months. I LOVE it! I also have a Huskylock 905 I've had for about 4-5 years and I've never had any problems. It's a workhorse. I bought it to make diapers and it was the only one after trying out several that could handle all the layers in a diaper soaker. It sews through them like nothing, no hesitation or skipping.
