Well, I don't want to be greedy, but if I can pick em up I will take all you want to give me

20 would get me rolling pretty good also, shipping here would probably be about the same I geuss or close.
I can always use batteries. I have a few projects in mind for indoor use that I would not want gassing of lead acid batteries or any leaks. Also may like to play with some high power devices.
I have a 120VAC electric heater, the temp settings go up to 170F on it. I looked at 120Vac elements today and also the temp controls. Not very expensivew for either, both run $6 to $12 each I think depending what you buy. So the most expensive of each is still only $24 for a set. Far less than I would have expected. I wonder if 120Vdc would work as well as AC 
Looks like I can make a decent electric cooker anyway for cheap.
One of my thoughts is the electric tank will have alot more draw in amps while the element is heating but it should really be equal power used as with a smaller heater.
The large one should heat faster and then cycle on and off as needed. The smaller one takes forever to heat up and cycles on and off more often. But I think it's still going to be the same total power used. Problem is the larger one will need so many more amps when it does kick on I could have lots of battery power that would run the small heater but shut down under the load of the larger one. I may try the tank on grid power at this house so I don't have to worry about batteries for now.
I am trying to get a small gennie flying at the other house now. Got some stuff yesterday but no time to work on it, maybe tonight I can alittle.
My friend is closing his salvage grocery store and that is keeping me a bit busy right now too. I just unloaded the trailer last weekend and got most of the stuff put in a building, but still had banana boxes with lots of broke bags of grits and such sitting in the yard. Ohhhh, I hate to go over there today! We had a really hard rain here tonight, bit of a hard storm for a short while. I bet I got a yard full of wet instant grits 
Got to get another trailer load today or tommorrow.
Good news is the mash I made up sunday is going nuts now. I hope that is a good sign.
Left sunday right after mixing it and was getting no bubbles, Monday I had decent bubbles, yesterday it looked like holding an air hose under water! I mean I was getting enough bubbles I might have been able to run an airbrush or other low pressure/volume air device from the barrel.
My barrel that should have been done a week ago finnally stopped bubbling now also. I should have about 30 gal now to try cooking.
I think the one jug turned to vinagar after I let it sit for awhile after I got the burning drops. Could be the 5 gal may have soured also? Problem was those darned balloons, they just fall apart or get ate by the Alky and fumes. Then once the balloons disolve air enters the jugs as it wants. Was not much of a problem when I was fermenting, I kept changing them, but while sitting so long it was a problem. I should have found something alot better and corked the 5gal one.
It should not happen again! I am thinking now that since I plan to always have a barrel fermenting I might be able to fill a barrel with CO2 as I empty it. Use the fermtenting barrel to "pump" CO2 into the finished barrel I am removing mash from. Maybe drop a tube into the mash a little up from the bottom and use the CO2 entering with a tube in the top to push out the ready to cook stuff 
Sort of a pump and siphon both but no air entering to sour anything that stands for a period of time.
Using free garbage I am mostly just out of my time if a batch sours I supose but if using sugar I'd be out some bucks.
Well gotta run, time to take the kid to school.
