Poor wallet! Any suggestions on a set of things to get to build my first own Keyboard?
Not sure if you have Princess Auto out east, but they're a great source for cheap tools, should you ever be restoring old boards or harvesting rare switches. Picked up a precision tweezer set, precision plier set, soldering pick tools (great for harvesting switches), alligator clips (for your multimeter, to test switches with), etc. etc. all for under $5 each.
They also have some cheap irons (which might be all you need for dealing with switches), solder, flux, and other necessary stuff for cheap.
I'd invest in a better iron if you ever think you're going to solder anything beyond switches or a Teensy. I have a Hakko FX-880D and it's such a step up from the $30-$50 cheapo irons.
Find some old boards and start disassembling and experimenting!
