Absolutely:
You did not say that does not read punch tape or punch cards
My
MaxNC 10 was < $2,000 used with software and some tools.
My
MaxNC 15 was < $2,000 used with software and some tools.
My
MaxNC T2 was < $2,000 used with software and some tools.
My CNC retrofitted
Sieg X2 with Freak mods from Hoss was < $2,000 with no tools at all.
My manual ShopMaster 2000 with CNC plates ready to be populated was < $2,000 in 2004 with a box of rusty tooling.
If you watch long enough you'll no doubt find a Bridgeport or clone that has a retrofit but again you might find yourself with a 19" computer rack and it may read punch tapes or punch cards.
To put this simply: G-code is older than you high school kids.
If you can find some used X/Y/Z tables with steppers you make a CNC very easily.
