Trace PS2512 [RE-wrenches]

[Jeffrey Wolfe, Global Resources]

Dave,

We have one PS installed in Strafford, a 24V unit. So far so good. Seems to 
provide good value for this customers dollar, and with out the click and 
clack that you got for free...

It is installed in a remote shed, so noise is not an issue. While it's not 
an SW, it IS cheaper, and these folks are watching every $, and are willing 
to live with the compromises they make. I do not recommend PS's unless I 
see this kind of acute $ saving situation. and fairly savvy clients who 
understand the tradeoffs.
