So a month or so ago I purchased a Simple (kit) from Printrbot.  Built it and it has been great!  The one thing I didn’t like was blue printers tape everytime and that the printout really stuck were “interesting” to remove.

I was on Printrbot’s site and saw they had a heatbed upgrade for $30 that allows you to use ABS plastics in addition to PLA.  But most importantly, it replaced the printers tape with Kapton.  $30 bucks is really inexpensive but consider this; you need a Power Supply.  So I dished out about $60 bucks for a nice power supply and another $30 for Printrbot metal stand/PS holder.

The upgrade was easy enough to do and I got my first printouts going in no time.  My daughter and I are having fun both designing and printing some online models now.  My suggestion to you is that if you are thinking about this printer, just get this upgrade up front and build it in.
