3D Printing of Small Bracket

[CRMS]

I'm looking to get a small bracket, stl attached, 3D printed and know almost nothing about it.


I have got 3 quotes:


0.178mm slice in ABS Stratasys £49 Black/White
0.100mm slice height in MF Onyx £57 Black
or 0.25 mm slice in ABS Stratasys £80 Not sure on colour.


What difference would I notice between them all?? I am tempted to go for the middle priced one??
