Reference the draw scale, I posted the following on another thread. I hope it helps!
I was looking for a scale for my drawboard and after a lot of reading decided to try the American Weigh H-110. I went on ebay and found one lised by libra6210 $19 shipped. Because I had heard there are knock-offs around, I sent her a message asking if it was a genuine AW scale and if she would ensure it's accuracy. I got a quick response back saying they only sell genuine AW scales and that if it was not accurate, I could send it back for a refund. So I ordered the scale. I got it last night (it is a genuine AW) and put it on my drawboard. I read the peak weight of my 60lb Alley as 59.76-60.4 (that is good enough for me). It would be nice to have the peak hold feature, but for use on a drawboard, it is actually better, IMO, to have constant read. The only other thing is it shuts off automatically after 60 seconds of no input. To get around this, you just hit one of the buttons every minute or so and it will not shut off.
Also, the scale is very compact,< 8", which is nice on a drawboard. The body is metal and it seems well built. It also came with a 10 year warranty.
Overall, I am very impressed with this $20 scale. It certainly will do all I need it to and more!
