I would suggest that you could buy a better quality used pair of calipers at a hockshop for about the same price (except probably for Hobo Freight). When I first started working in a machine shop, I bought a pair of dial calipers and 0-1, 1-2 and 2-3" micrometers, all Mitutoyo, and still have and use them all.
What I have done several times in such a place is to look at what they have, ask to hold them, see how they function, and make them a "cash money" offer for the bunch. Got a Mitutoyo depth micrometer the same way. I've used this stuff for 45+ years. Most of my dial indicators were bought new, and all these tools used to get calibrated either monthly or frequently. Good stuff lasts and holds value.
One of my prized posessions is a drill index with number, fractional and letter sizes. Well, that and a PA .51...

PS: I like a .161" drill for 4mm/.156" spraybars like ST, K&B, Randy Aero, etc. That's a #20, BUT that's also for my own Delrin venturi/restrictor inserts, because plastic always drills under actual drill size.
