Edit to add; - I buy the cheapest hot plates I can find - usually from secondhand stores - why - because with the corrosive chems used in refining they usually need replacing sooner rather then later anyway

I also prefer "enameled" hotplates rather than the stainless ones, they hold up a little bit longer.

If you want pinpoint control on any electric hot plate, plug it in to a Variac (variable transformer). Every lab I've ever worked in had a few of them sitting around. I bought a big heavy (a guess of 15-20#), brand new one made in China on Ebay a few years ago, for $99. I got it to use on a one speed (way too hot) electric smoker, to give it a full temperature range. Worked great. I've also used them on lab stirring motors (prop type) and they supposedly work well on the manual (only - not the automatic ones) type of battery chargers.
