Product review (5 stars): Piece of cake
Easy replacement with the wife's help.  I did have to do the wiring modification for my dryer, but easy instructions and all the necessary parts are included.  We tore it apart, vacuumed the whole cabinet, reassembled it, and had it drying a load in about 30 minutes.  You can pay $179.00 if you want, but you'll get the same box I got for less than $50...
