Which VTF Scale are you using?

The digital scales can be off. I check them with little calibration weights.
The Ortofon I currently use is right on but it sits awkwardly on my gizmo so I ordered a Riverstone which should work better. It looks like a great product for the money. People here seem to like it.
The Musou is sold under 20 different names and costs anywhere from $12 to $129 for Pro-Ject's version. So much for exclusivity. 

I use a 20 year old WallyScale.  While it is somewhat Rube Goldbergish, it still works quite well.

I got a few digital scales from ebay a few years ago.  They look identical to the high-end ones that are sold in the U.S., but cost 1/10th the amount.  Work just as well.  All they need is a logo to be indistinguishable from the expensive ones (probably the same unit without the logo).

I noticed they were bringing it back but their other stuff is SO expensive so I'm guessing it will cost an arm and a leg.

Is this device worth the bother or is it usable for not super accurate measurement?............
