i'd go with keenovo. expensive but wont burn your house down.

here is a controller (42usd) https://keenovo.store/collections/ac...ge-of-30c-300c. the controller @110v has a capacity of 1600 watts, more than enoughph for a 3d printer (like 400 watts?)


idk what size bed you have, but this controller needs a mains powered bed (i.e. 110vac or 220vac). fast heat times are a benifit of mains, also you wont need an extra 24v or 12v power supply.

here are where to buy a bed from: https://www.keenovo.com/info/shop.html
