My two go-to HF grinders have paddle switches. They cost me $20 each, but they only sell that model in stores now, so won't ship another to me. I also have another HF grinder with a slide switch, and I agree it's hard to use with gloves on. I killed one of the bearings in it, but sometimes use it for rough work like with a cone wire brush, and don't care if it completely dies. That one was $10.
Two grinders is a good plan. But two name-brand ones gets hard on the wallet.
