well to start with you can't buy a tiko yet.
probably be available sometime next year.

Of those you've listed the monoprice maker select (actually a rebadged wanhao duplicator i3) is easily the best.

The nicro 3d has a lot of issues
the other monoprice is just teeny tiny, and as mentioned you can't buy a tiko yet :-)

You might want to consider throwing a little more money at it and getting the i3 plus: https://www.amazon.co.uk/Wanhao-i3Pl...+duplicator+i3

Or the 2.1 - https://www.amazon.co.uk/Wanhao-i3v2...+duplicator+i3

I think the monoprice is the original v2. Still a stupidly good buy, it has to be said.
