I have the Snapmaker 250 and its an awesome product, absolutely top shelf in terms of print/carve and etch. Mine is the 1600mW laser although there is a 10W now available as well as a rotating axis for carving chess pieces and the like.
The 3d printing gets most used followed by the laser etcher. And the kit certainly brings out the creativity, attached is a handy holder for my AsiAir wifi range extender that I designed and printed yesterday
Unfortunately, the v1 from jaycar has a very weak laser and I'm not sure that the 10w is compatible as an upgrade (albeit a very expensive one). I think the 1600mW is and you may be able to find one second hand as folk upgrade.
Would I buy one again? In a heartbeat
