The machine I use the most is Brother 1500SL. It weighs about 50 lbs and large enough it's not easy to pack. Then a Bernina 770, same issues. I bought a Nicchi without doing my homework. I love the machine. It's not as heavy. The size is still large. I like the machine and use it now as my traveling machine. Since it cost a lot less than the Bernina, it can be dedicated to travel where its gets vibrated. It stays packed. It does have all the features I want, except it's computerized.
I think if brother made a smaller machine just like the 1500SL, that would be great.
