Hello Julius!
It's difficult to choose an LCD for you. It depends on what you want to make with it.

However, if you want an LCD that can be used for diagnostic, this is clearly not

Here are for a quite wide variety of applications.
If you need a low power device, take a black & white COG LCD. If not, then you
may choose a color device.
