Thanks guys (and gals) for your replies, will let you know what we decide this end. We are also after prompt, and reliable after sales which Dell are not too happy about, they won't let us keep a buffer stock of parts and we have to call them for stock or they will send an engineer etc, to do stuff we do on site anyway.

We have had a Dell salesman here and are waiting for Mesh and Evesham.

Fingers crossed we don't shoot ourselves in the foot (feet?)

Cheers again y'all!!!
