52 Weeks ?
They must be kidding...

Anyway, the E-Muser uses the $18 Teensy 2.0 board without pins BUT you'll have to solder 5 of those pins yourself then (because only 5 pins are used).
You could order the version with pins to avoid the soldering, but in that case a small change will be required on the printboard to avoid shortcuts (a very small change, don't worry - I might indicate it even in the instructions...)

Compared with the EmuComBox, some additional electronic components are used in the E-MuSer (just for comfort purposes):
- 1 standard green and 1 standard red LED
- 2 resistors of 330 Ohm (for the LEDs)
- I used 4600 Ohm resistors instead of the 5100 Ohm ones in the EmuComBox, but that is not important... 
- one standard (cheap) printboard with cupper lanes on it, either epoxy or cardboard sized minimum 6 cm by 6 cm.
- 1 DB9 SUBD female connector.

For cases and cables it depends on your needs and wishes; the print design allows for cases/housings as small as 6.3 by 6.3 cm.  
For mechanical stuff e.g. to attach connector and other components to the printboard, you'd better wait for the build manual.
You may have to order or shop for additional parts for that...
