>How does one select an electric turn coordinator?
I selected the one on offer ex-NATO (and actually built by Smiths 
just up the road from my house) at my local PFA strut (like an EAA 
Chapter) for 35 UK pounds. It is a little heavier than the sparkly 
new ones from the catalogues, and I will have to build (or if really 
lazy, buy) a 24v inverter to drive it - but at that price, I'm not 
complaining. And I can afford to replace it several times with the 
same type before approaching new-instrument captial outlay. Oh, and 
finally, it's a proper turn & slip with a needle instead of one of 
those misleading little aeroplane symbols!
I realise my particular experience is of little use to you, However, 
you might have a look at what's available at the S/H instrument 
stalls at Sun'n'Fun & Oshkosh (sorry, too late for this year), or 
even your local homebuilders gathering, if you want to save serious 
amounts on panel stuff.
