I find simply putting them on an oiled tray lined with foil and into the oven at
a low
temperature does the job. Where I am, gas is cheaper than electricity and I
don't
like the constant noise of my dehydrator motor fan going.

Picked up a food dehydrator for $5 at a thrift shop. Still drying my
first try. It's been on over 24 hours. Some are still not done while
some on the bottom tray are toasted. I couldn't slice them a uniform
thickness. Don't know if I'll get any more ripe tomatoes for a second
try It probably cost me a quarter a batch for the electricity. Can't
wait till next year's crop to do more drying.
