Aspire seems to be the go to software for CNC routing, so out of curiosity (I could never afford it!) I looked up the price. From Vectric it costs £1500 for v11.

There were however search results from a site called Wish and AliExpress offering v9.5 for around £30 and v10.5 for just over £50. There was no support option though. Mmmmm, I wonder why!
