Hi
I have the 720 which is less than a year old and i like it for what i do but it has not come without problems.

If you search for my posts you can catch up with the problem i have regarding speed and yes the cost implication of getting the screw sorted is high. I now run at a much lower speed and get some great results but as Jazzcnc and others will tell you for the money i paid it should be running a hell of a lot quicker. As i cant afford to build or get another model i live with this restriction so my advice is definitely dont over drive it, if you cant live with low speed for whatever reason then its not going to be much cop for you i imagine.
I use WinPCNC which when i ran the setup all the default settings are there, i dont know what you will use but if i can give you a setting or 2 i will try.
I am a novice so would not give you advice thats really for the experts i just hope this adds a bit of info for you
