Does anyone know of a source where I can obtain the button without being price-gouged on postage?


It cost the same to mail a $2 button as it does to make a 2K diamond (assuming you're not adding insurance), so I wouldn't call it "gouging"


Also, how easy or difficult is it to install the button? Will I be able to just pop it in or will I have to unscrew and disassemble anything on the unit?


Look at the knob: if it has a flange wider than the space it takes to insert it through the vacated opening, you'll have to remove the transport. OTOH, if it does require transport removal, you can Dremel the button down and snap it in from the outside if you don't mind the wider gap that will result from the trimmed plastic removed.
