Had a beta 3uP and recently found the time to upgrade to the 1.5.1. Features:
1) BPopilek cable chain
2) BPopilek feet
3) E3D v6 hotend (needed a washer on top to fit snugly with extruder) - features a stainless steel nozzle
4) Bulldog Lite Extruder
5) RAMPS 1.4
6) Octoproint using a RaspPi. I used to use Astroprint but it doesn't feature live streaming of the print, just time lapses. Pretty cool too because I vpn to my home network on my phone and am able to control and watch the progress while at work.
Let me know if you have any questions.
