Radu,
I picked up a Tomlov brand digital microscope that is handy for soldering and board inspections. There are several styles available on Amazon for prices as cheap as $70.
The advantage to it is that it has a self-contained LCD display so is a single compact unit to use without having to connect wires and cables to other equipment. It even has the ability to record to a USB drive if needed.
The model I have is a DM201 with a 7" HDMI display. If I can recall I paid around $130 for it. It looks like it has now been replaced by the slightly higher priced model DM202. But there are many other models available. You might take a look at them
