Turns out Lowe's sells the ceiling tiles individually for $4 and change. Attached is the picture of my increasing number of building supplies. Not shown is the 4'x2' ceiling tile and 50lb. bag of sand which are in my garage awaiting use.
Just for the record, almost everything you need at Lowe's is in the Paint section (as opposed to the woodworking areas). Go figure.
I did not get a soldering iron yet, as Lowe's doesn't carry solder or flux paste (apparently not this one anyway). I'll stop by the mall on my way home tomorrow and get it all at RadioShack.
I'm hoping to start building tomorrow afternoon! I want to take the plans in to work with me before I mess them up and digitize them so I'll be able to print fresh copies in the future if I need to (we have a scanner that can read sheets like four feet wide and any length, it's impressive).
EDIT: And, of course, I forgot to actually attach the photo!
EDIT 2: Did you mean to call them "Home Despot" Bruce? If so...
