There's a portable engine preheater on ebay motors for $129. It looks
like an ok unit but I'm asking for any of the collective wisdom on pros
or cons of a unit like this. There's also one on Sportys for $399.
Any opinions on either or a comparison?

What kind of pre-heater are you looking for? Something you can use to heat
the engine relatively quickly, or something you can leave on for several
hours before flight to warm the engine? What is your climate (e.g. how cold
does it get where you live)? Do you need a heater for one plane or to share
between multiple planes?

Personally, I have one of the Reiff hot strip systems which is a sump
heater. I get 100f oil temperatures on start-up after a 4 hour heat cycle.
I have the thing attached to a timer so I just set the timer to come on 4 or
5 hours before the *next* time I expect to fly.
