<div class="PlainText">We have a Cressington Turbo Carbon Coater 208 Carbon and we are very
<br>
happy also.<br>
You can combine it with a glow discharge module also.<br>

Leica EM ACE600 didn't work nicely during the demo and I think the <br>
consumables were quite expensive comparing to the carbon rods for <br>
Cressington.<br>
