This is a list of mail order companies of different countries where you could buy the components. The tips where collected by MIDIbox Users in the last few years. Note that I cannot guarantee that these distributors offer the best prices. If you know better shops, just add them here (hey, thats the power of a Wiki!
There are a couple of sources of circuit boards, parts kits, programmed PICs, etc. within the MIDIbox community. Details at where to order pre-made printed circuit boards pcbs and parts kits
ALPS STEC16B02/03/04 and STEC11B01/02/03/04 (detented/non-detented type) at Distrelec (Switzerland, Austria, Italia, Poland)
318-ENC160F-24P at Mouser for US $2.59
http://www.pollin.de/shop/detail.php?pg=NQ==&a=Njg2OTU3OTk= German Seller, 16 detentes - nice & cheap 0,75.- Euro/Piece
M-SW-ROT (detented type - very good quality, very fair price, fast delivery!) at Voti (NL) for around 1.20 Euro. Note that the pinning is the same like for ALPS STEC16B - see also http://www.voti.nl/common/sw_rot_1_doc.gif
(Don't be shy about ordering international - prices vary a lot!)
You can order all components at http://www.reichelt.de (cheap and fast!)
PIC18F452, LCDs and cheap rotary encoders: http://www.voti.nl
PIC18F4685 and other components: http://www.farnell.de
nice LCDs : http://www.tronico.net
Encoders, cheap LEDs and more : http://www.pollin.de
PIC18F452 is available at Gamma for ca. 38 Zlotych. 16×2 backlit LCD for ca. 30 Zlotich in (nearly) all shops for electronics's hobbyists or at AVT. STEC16B03 Rotary Encoders can be purchased at microdis for about 11.50 Zlotych.
Don't order from Farnell or RS-Components, you can get it 90% cheaper elsewhere. Shop around! Good local stores like Jaycar and Radio Parts General have most of the components at reasonable prices, but you can get things much cheaper from Australian electronics distributors such as Rockby Electronics for resistors, capacitors, sliders, pots, chips etc. and Switches Plus for harder-to-get things like ALPS switches, rotary encoders, sliders, pots, etc. Another retailer for PICs: Dontronics.
A great source of harder to find LCDs in Australia is Crest Technologies. They stock PLED's as well as various Character LCDs and Graphical LCDs. They pack their products well and ship fast. Another great supplier is Aztronics who have a lot of what you may need and I think ship nation wide, they mostly stock product from Altronics. Aztronics stock rotary encoders almost all the time and they are reasonably priced.
Distributors that distribute for many different brands. If you wanted to get Everything you needed for one project on one bill, you'd probably go here.
Distributors that are more specialized in the types of products they sell
Companies that specialize in LCD and LED displays
Companies that specialize in Surplus, Used, New Old Stock (NOS), etc. They're often good for finding interesting parts or rarities

The problem is that everything is cheap until you try to ship it all the way to New Zealand!!! - I was quoted $19US for 32 sliders from Song Huei in Taiwan (awesome!!!!) but $50 US postage!!! (bummer….). Similarly, I could get a PIC for $6 US, but add $25 US postage and it doesn't look nearly as good. (Rest of components from Dick Smith Electronics)“
Mail by Rowan Spicer: “During the first stages while pricing parts from various sources I discovered a very cheap (By New Zealand Standards) and helpful supplier. All of the parts for the PCB including the A 16*2 LCD cost less than $100 NZ ($1 NZ = Approx $0.50 US) I've included an invoice to show the price breakdown: NZ pricelist. (Note by TK: the PIC18F452 requires a 10 MHz crystal!)
- weight to 2Kg, order 50…300Lt (~15…87EUR) - delivery cost 9Lt (~2.6EUR);
- weight from 2 to 5Kg, order 50…300Lt (~15…87EUR) - delivery cost 11Lt (~3.2EUR);
