Did my whole cabinet using the $59 bucks Ryobi at Home Depot.  Work out great.  And after you use the sucker, you will go on think why didn't I buy one earlier as there's so much other things I can do with it.  Picked up the slot cutter bit at Lowes cause home depot didn't have them available.  
And BTW, cutting plexi glass with the flush trim bit is a piece of cake, don't even need to sandwich or anything.
