Recommendations for an engraving machine

[bsainty]

I am new to this site, so hello everybody.

Looking to buy an engraving machine with a flatbed of around 600mm x 600mm, maybe bigger or smaller.

To cut in mainly aluminium, but maybe on occasion stainless.

Would like a good quality machine, dont mind paying the extra.

Have been looking at the gravograph machines and vision machines, but to anyone with great wisdom could you recommend any other brands or there knowledge in this area or what to look out for.

Thanks in advance
