Steppers $12 for one Nema 17, and $5 each for three small steppers (the small ones are all that is needed for X/Y and feeding the filament). Steppers from Adafruit.
Propeller Proto Board USB, $20 each (if you purchase them 5 at a time, as I always have).
ULN2803's, $2 each, and I am using 3.
Linear bearings, $5 each (could print them for less than a dollar each if I had access to another 3D printer during construction [and use BB's for the balls]).
8mm steel rod (purhased in 6 foot length) for rails, $8.
Wood for frame, print bed etc, less than $7.
Steel and NiCrome to make hot end, $5.
Screws less than $1.
Epoxy less than $1.
Voltage regulators, less than $1 (bulk from Digikey).
Some of the wood was used for the driving spools, and fishing line is used instead of drive belts.
And a few nuts and some all thread for the z drive, $10.
That is less than $120. Though beings that I am half asleep at the moment I may have left some things out, so the $140 I mention above is likely closer to the truth.
Note that I did make some changes to the design as I went along, so I spent over $200 on it as some things got replaced, do to design changes.
So yes I included everything.
As to aesthetics, not that great, though could be made to look better with out any additional cost. I always count everything, including the purchase cost of those things I already had laying around.
