Regarding HF, I have a 3" cutoff wheel (pneumatic), 4" angle grinder (pneumatic), a sander/polisher (electric/corded), and the oscillating tool (electric/corded). Aside from the odd cut-off wheel size, they all work fine. All combined they weren't likely $50, and get used a handful of times each year. Can't complain. Do they use more air or are noisier than their name brand counterparts? Sure. However, for no more than I use them, it doesn't make sense to get fancy with them. I'm also not particularly brand-loyal when it comes to most of my tools.
