I need to re-zero every time anyway, so I'd rather not have to replace the battery every few months. Really, I'd like a mid-range model; not a cheap one or a cheap one sold for more, and not a high-end one, just something that works reliably and repeatably, and doesn't chew through batteries. I have a ~20 year old (guess) set that fits this description, and several newer cheap and crappy ones that do an okay job if you keep spare batteries on hand. It seems impossible to find more like that old one.
