DXF,SVG and png bundles packages ?

I would like to know if you guys/gals ever use any of the above type bundle packages, the packages on etsy have anywhere from single, 500 to 100,ooo different artwork for different prices. If you do what do you think of them ?
Is there any you could suggest if I decided to purchase ? Any particular ones to stay away from ?
I do CNC Plasma and CO2 laser along with some wood CNC
Thank you


Haven’t purchased any file bundles, but I’ve gotten a few things from here.
A wealth of knowledge and if you contribute $20 you are able to download shared files. I’m sure most of them are more cuttable than the ones in a random bundle off Etsy.
