For a surface, I'm using perforated board and a 'raft'.. No lift or failed prints. (well, very low percentage).
Started to make ABS Juice the other week, will try that soon.

I did try the bluetooth on a sanguino but moved away from the sanguino. Looking at a build chamber next, maybe a small barrel type with a perspex window

Had a dual extruder, but the motors I used went really (extremely) hot really quick and made my bracket melt on one side.. :S Moved back to single.

Bowden is nice. Great looking piece.
No neons yet - I found an LED piece which you solder onto the heat bed to illuminate the print area.
