I have an older model the flamefast ds250, its perfect for someone who has a few hours per week to forge and doesnt have time for messing around with coal, turn it on, it heats up in about 15 minutes, when finished turn it off and home. They are expensive new, all kinds of safety stuff as the flamefast models are used in schools. I got mine for around 250euro from a school that was trading up to the latest model due to new safety requirements.
