For my first venture into CNC I thought I would buy a Sain Smart Genmitsu Router 3018-Pro. This is the low end of CNC engravers and at the time mid-2020 was around £200.
The reason behind the purchase is primarily to make brass nameplates for some of the engines, including the boiler door engraving for the miniature traction engine project. However, the more I read about this the more I want to also use this to carve wood in 3D.
The package arrived in around 3 days and I have to say it was an exciting unpacking and assembly process.

Must admit that the assembly process was very straight forward, a rather simple manual that is easy to follow if you take your time. The part quality was very high, the only questionable features are the spindle, spindle motor that are rather crude. Also, the T-nuts and bolts are not that great, I will be making some T-nuts and tidying up the fixing system.
I will add my experience of using this as I go, next step is to look at the software and see what design options I have. I also need to add a page on CNC so that I can share the knowledge as I go, ok this might take some time as this is my first venture into CNC.
Early days learning and software that you will need to get started.
Just had to make some proper T-nuts that work in the beautiful extruded aluminium table.
