Please note that this is a rather expensive commercial grade heater running on 220V-single phase power. Also, since this burner operates using magnetic induction you can ONLY use steel cookware for your pans. My experience with these burners is that you really need to watch how quickly you heat thinks, too quick and the foods might scorch.
Shipped this was less than $200, not too bad under my budget. I am not afraid to fab up anything to save a buck, but this is really pretty cheap for a very nice induction burner that has a bunch of useful settings. Consider that this burner also has multiple uses and it's value/cost ratio over a home built immersion heater in my opinion wins out. I also use it for making hot water to sanitize parts and tubing and boiling decoctions. I have also used it as a HERMS unit with a grant (pictured insulated pot) for performing stepped mashes. Not to mention it's obvious use of cooking food for parties and such.
It is true that this burner requires induction ready pots, but due to the popularity of induction ranges in the home, most commercial pots work, including the pots from Morebeer and Northern Brewer.
As to burning or scorching, I use the Update International pots (same as Morebeer and Northern Brewer pots) and they have a nice thick bottom and do not scorch at all. The burner has multiple settings and makes temperature control very easy and hands-off if necessary. No need for controllers or home-built wiring circuits.
It also meets the O/P's needs. If his house has 220V for either a stove or a dryer, it will work in his apartment. No risk of fire and does not get hot. Add a small pot (grant) and it can be used as a HERMS for stepped mashes even with a cooler for a mash tun. Portable and comes with a warranty for under $200.
