I use a variety of belt sanders in the shop, and wouldn't be without them, particularly for metal work, so this isn't the preachy segment of the thread. However, if any of what you are doing could be done with a hand plane, particularly wooden, it would be a faster and more friendly world for you. My hand held belt sander is really old, an early plastic makita. So can't help you with your purchase. I would like to get one of those old PCs that looks like a choo choo.
