Looking for laser machine recommendations

Hi, I’m from the forgotten state of Tasmania in Australia.
Currently using a 20w fibre for coin die engraving.
We are looking to upgrade to a more powerful machine with a lens suitable for deep relief engraving.
Does anyone have any suggestions to machine makes to look at?
Ideally apart from coins, I’d like to be able to get decent depths for other applications. A depth of 2mm would be nice that doesn’t take forever to process.
There is a myriad of machines now on the market and it’s hard to know what we may need. So hopefully someone out there may have some input to machines and lenses.
Cheers Rolf.
