printer choice - advice

I am new to the forums and as such, I apologize if this is a repeat post. In my defense, I did search through the forums to some degree to try and avoid duplication.

I have a budget of 300 dollars and I am looking for a 3d printer for my lab. I would like flexibility in my printing material choices and quality in the printer itself. I have been looking at the prusa i3x, but I am just not sure. Any advice would be very welcome.
