I did one like this - http://www.amazon.com/gp/aw/d/B00I50G42A?pc_redir=1414374074&robot_redir=1
I like it, but I can't recommend it over a "normal" pcb-type bed. The only real advantage it has is that the thermistor is embedded in the heating pad.
This is the heater I bought:

Another option I didn't mention is to get a separate, adjustable voltage power supply and feed higher voltage to the bed heater PCB alone via a relay. Even a 24V power supply is probably safe here, though I would encourage you to do the math and use your own judgement to be sure. You could use the stock laptop power supply to run the printer itself.
