Thanks Gary. I found this unit about a half hour ago and sprung for it.
I'll have to wire up the PPS, but I'm willing to give it a go, 
particularly on something that cheap. If I kill it - oh well! No gotchas 
in the listing details that I can see, other than possibility it won't 
have a battery soldered on, but that can be overcome as well.

Yeah, I may have to wait a while for it. I'll live!
