I have a couple here and i'd be willing to sell one.
In my current financial situation I probably shouldn't even ask, but I'll tell the girlfriend I'm only asking. Then maybe a "Wow, the windows work!". How much would you be asking for the timer relay board? And where are you from, is postage going to make it more worthwhile for me to go hunting through some electrical shops; that's if it works out that I can work out how/where to install it.
I'd prefer not to go for the auto winder:
a) No Alarm if the plan is to turn it on that way.
b) It's been ridiculously hot lately and sometimes the windows need to be left down a bit
