I second this. I also bought an Ender 2 for $200 that came completely flat-packed. I had 'fun' assembling it and had several months of 'fun' printing parts for the printer and buying upgrades. Most of which I managed to install before I got tired of every other print still failing and requiring hours of fiddily tweaks to print nicely. It is collecting dust now as I obtained a slightly nicer Monoprice Duplicator i3 secondhand which still fails pretty frequently unless I run it at 20% speed.

If it is within your price range I would highly suggest a printer with Auto-Bed-Leveling, will hopefully mitigate some frustration.
