with the price of copper going up, i have decided to actually buy a premade condenser but looking around for standard air cooled types it seems they do not come in a small size (smallest i found 36x48 at united refrigeration)

i seen some people use saws to cut up larger units, and tbh i don't want to take that route so anyone know who makes smaller condenser units that are made of copper?

secondly would heater cores work as a condenser solution or will it not be enough to liquify the refrigerant?
