If you've had the pleasure pleasure of owning an antique machine and then purchased a new sewing machine, you may have noticed one major difference as soon as you picked up the box: New machines are generally much lighter than their ancestors. Older machines were typically cast iron beneath the surface, while new machines are filled with many more plastic parts. Newer machines aren't quite the workhorses that their predecessors were, but if you're taking lessons or classes that require you to drag your machine around, you may not mind so much. Lightweight = Easier to transport. However, the first time said machine tips over or your serger goes dancing off the table and crashing onto Rover, you'll see the obvious downside. (Ask me how I know...)
