Auto draw-off or Pre-heater?

[binski]

Looking for suggestions/opinions if you would purchase an auto draw-off or preheater if money is limited. Smoky Lake has a variety of auto draw-off's ranging $500-$1100 and a preheater/drip tray for my 2x6 for about $750. Thanks:confused:

I went with the preheater when I ordered my 2x6 evaporator. The water will be useful in the shack.

Of the two would go with the preheater first....you will boil more gallons per hour.
