 Needing a quick solution to a heated bed, I dug around my closet and found this $20 GE hot plate that I had used to do some SMT soldering.  I purchased the 8"x8"x0.25"aluminum plate at a local welding shop for $5 and covered it with Kapton tape. I used a bit of doublestick tape to hold the hot plate to the McWire platform and some more Kapton to hold everthing down.  I "borrowed" my wife's thermometer and taped it to the bottom of the plate for a quick way to measure temperature. 

 So far it has worked great and ABS parts come off with ease.  This solution isn't very elegant or complicated but it gets the job done, took less that 10 minutes to build and test and cost under $30 for all the parts including the Kapton. It probably wont fit on anything other that a McWire or gantry style machine with this size hotplate but you may be able to find a smaller one in your area.

Here is a photo of Mendel parts printed on the bed. Its about 25% of the RP parts needed.
