The original request was for a constant current load. Heaters would be a near linear and somewhat constant load impedance. Current would be proportional to voltage (and inversely proportional to temperature most likely). But certainly not constant.

Looking for something maybe 2kw+ and the cheapest premade thing I can find is $3500. Maybe I'll just use a carbon pile load but that will be much less accurate.
