Rather cheap CNC?

I've been looking into buying tabletop CNC machines lately ( I know you can make your own)
Have a look at this CNC machine
http://www.taigtools.com/cmill.html
The price tag is ~$2200.
Is that a normal price for it ? or perhaps there is a cheaper CNC with the same amount of accuracy?

That's about the normal price for a complete CNC Mill. A sherline will run you about $300 more, but it is a Sherline. I always recommend starting with a sherline lathe and building up from there. The sherline lathe has an attachment that turns it into a mill. Building up on the system a little bit over time costs a little more but it is easier to shell out $200 here and $100 there, than $2500 all at once.
Of course I still have not switched to CNC, I do everything by hand because it will always be more accurate than CNC.

By hand more accurate then CNC? I would think it was the other way around. Of course my construction skills suck so that might have something to do with it

The steppers from CNC are only accurate to a certain range, where as the handwheels can be more precise. Working under a 10X maginifying light helps

Doing something by hand means with mechanical tools, not handwheels. There's one step from handwheels to CNCing

We use that exact CNC at work, (its the old and small one now but it still works) and its great for a first time user. We use solidworks and GCAM to run the machine. I don't know if anyone has ever used GCAM, but my mentor Justin Shumaker is the guy who made GCAM.

Yah I was thinking by hand meant with a hacksaw and a dremmel not a mill with hand wheels. I can see what you mean now.

Sorry, hung out with too many machinists in the Navy, if a computer does all the work it is CNC, otherwise it is by hand. Of course they also considered themselves artists, and seeing their work I could never disagree...

with a machine like a CNC , I would much rather buy it so that way I can get it serviced and then i get a warranty
