Ok. I have a portable propane model, so I don't have direct experience with
either of these. Both appear to be adaptations of the sort of "ceramic" electric
heater that sells for around $30 at Home Depot. The Sporty's unit looks like it
would do a much better job, since it pulls it's intake air from the cowl. If I
were using it, I would stick the discharge in the gap at the bottom of the cowl,
though.

I have two of these units for helping heat poorly heated rooms in my home. They
do that job very well. I even got decent results using one to heat up an
unheated garage -- it kept things from freezing, at least. Based on that, I
believe Sporty's claims about the efficiency of their unit. Dunno if it's worth
that kind of money, however.

The main disadvantage I see is that these units require electricity. They're
also not going to be weatherproof. That means the portability is of limited use.
