For engraving silver and gold plating: Diamond or spindle?

Hello all,
I have to decide on which engraving system I'm going to buy to engrave small silver plates (small medallions etc) and I'm trying to understand the difference between machines that have a diamond head and others that use spindles. Is there a noticeable difference in quality?
I had a demonstration of the Gravograph M20 (around 4500$)and the quality was great but it seemed unable to engrave evenly on rounded surfaces.
I saw a Korean machine (comengraver for around 2700$), much cheaper, but the quality I found was slightly inferior.
Both these machines use diamond heads.
I'm going to look at the Roland EGX 20, because apparently it has active surface detection that allows it to engrave on uneven surfaces, and it's pretty cheap compared to other machines (around 2500$?). Does anyone have this machine and can comment on its quality?
Also, do any of you guys use the Metaza photo impact machine? I don't like the photo realistic results too much but maybe after vectorizing the photos the results can be nicer.
Thanks a lot

"Diamond or Spindle?"

Concerning "unable to engrave evenly on rounded surfaces" consider a Newing-Hall engraving machine. The spindle is air driven and conforms well to curved surfaces.
