Viscosity measurement for batters, ideas yall?

Good morning all. I work for a dry mix producer. We measure viscosity on a few things, and have always used the old 'ramp' style viscosity chamber to measure. I'm looking at some of the rotary/digital ones. Does anyone have any tips, good bad experiences, a good model that's not hugely expensive?  I'm looking to keep it under $500 bucks if possible, and want something that's going to last. If not I'll stick with the antiquated but tried and true device. Any input from all yall pro-fesh-o-nals out there would be appreciated! Thanks!

This one is a rotational digital one:

SNB-AI Digital Viscometer.

Used it during undergraduate studies and it was really good.

I've been impressed with the Brookfields that I've used, but $500 seems an optimistic budget unless you get lucky with something second hand.

IMEX aside from the kit itself, it helps if you understand the rheology of the liquid(ish) that you're measuring to an extent - e.g. is it non-Newtonian, thixotropic etc - as this can have a bearing on what you measure, and how you and others would interpret the results of that measurement ;)
