Frage Another possible owner

Hi, All been reading as much as can on the forum. Sounds like everyone is fairly happy with their machines.
I'm thinking of an 840 with the 3d printhead. I'm wanting to do scale truck model parts mostly out of styrene. Lots of flat stock cut outs, plus some 3d work. Just wondering if there are any certain things I should be aware of, paticular options needed. Most of what I'm hoping to do is fairly fine intricate work,I build my models in 1/25-1/24 scale. I'm a cabinet maker so I seen larger machines do some neat stuff. Just looking for any advise or tips. Thanks Doug Walker Victoria BC CANADA. PS Anybody close to my location.
