it is not trivial to actually build and tune such a thing. To make the electronics for it to tare, etc. is also not trivial. Again, good meters to make the best scale are also not cheap when bought new. Thankfully, analog meters are very common used.
Also, remember, the manufacturer must guarantee the precision and accuracy of a meter they produce, over certain temperature and voltage range. The homemade version carries no such guarantees.
Lastly, remember the market for microgram scales is hardly a high volume one. The few companies involved may find it much more profitable to simply allow prices to remain high.
