+- 5 MX Red or MX Black switches: $8.50 - $10.00
+- additional 1.5x DSA keycap: $1 plus $8 shipping
+
+The base keycap set only has one 1.5x key, which is used for the inner
+thumb keys. You can use a 1x key for one of them, but it looks kind of
+tacky, so I recommend getting a second 1.5x keycap separately.
+
+*** Other Tools
+
+You'll need a soldering iron, solder, and a wire cutter. A multimeter
+can come in handy for testing the connections but is optional. You'll
+also need eight M3 machine screws with nuts; the length of the screws
+depends on the thickness of the acrylic you use. You can add rubber
+feet to the bottom to prevent the board from sliding around when
+placed on a desk. You'll also need sandpaper and finishing oil for the
+wooden cases unless you have bought a kit.
+
+If you are building a hand-wired board you will also need a glue gun,
+hookup wire, and wire strippers.
