You can get in engine block heaters that heat the water jacket of the engine in the US and Canada. Or you can get an in-line coolant heater also. I haven’t seen a oil pan heater in 40 years. They aren’t really a need anymore with 0-30W engine oils anymore.
A block heater will set you back about $120US installed at your local repair station. The in-line coolant heater is some cheaper being only about $75US installed. They both work off of common 115/120V/15A power. No fixed install required for either. At worst you will need to buy an extension cord of the proper gauge. Maybe another $50US. This is well below the costs you cite.
