Is there something legal and similar that costs $35? Or are you
referring to fabricating a heater using A/C duct and a blower? $35
won't buy you much in terms of a space heater.

I can't see how that would be as efficient in warming the oil as
putting 125 deg heating strips directly on the oil sump?

That's exactly what I do. I started with one glue on pad. In the
unheated hangar I was in at the time it didn't get my oil warm enough.
So I put a second one on next to the first. Now, with a Kennon nose
mitten on, the oil gets to and stays at 100F. Each CHT and EGT gets to
and stays at 80F. So for $35 for each pad I laugh at the fools who
spend $150+ for the exact same thing because Reiff, Tanis, etc put "FAA
approved" on the box. It apparently never occurs to anybody that the
words "FAA Approved" mean exactly nothing. What a bunch of lemmings.
