get used to the machine first before doing mods..
getting the rollers correctly set and the frame square at the start really makes life down the track much easier
i have a now heavily modified 3pro and its a great machine if you put in the time keeping things level etc
the more expensive machines need less tender loving care but the ender can produce what they do if you take the time to set them up properly
chep is pretty good on most things
