Re: Poor man DRO

Sounds like a neat project, but........
If you want a GREAT, Inexpensive DRO, then you need to get the
ShumaTech 350DRO for Chinese scales. They work great!!!! You can not
beat the value!!!!! Price and Features!!!!!!!!!!!!!!
They have their own group at http://groups.yahoo.com/group/ShumaTech/
This is in kit form. You must build it yourself.
I have three. I am not affiliated the ShumaTech in any way... other
than belonging the that group also & owning the dro's.
Thanks, Tim Bostic
