There isn't an "Other" forum, so I figured I'd post this in here. I just happened to stumble upon this Inidegogo project from RepRapDiscount (maker of the LCD display unit). From what I can tell, it does more than the RAMBo and at a lower price:
RUMBA (R.eprap U.niversal M.ega B.oard with A.llegro driver)

* fully integrated all in one solution
- Arduino 2560-R3 compatible (works with Sprinter, Repetier, Marlin out of the box)
(easy to change/flash firmware for end user)
- ATmega16U2 (with enhanced firmware) for high speed USB serial connection (up to 2MBit)

- can be used with 12V-35V for motors / heated bed
- integrated high precision power regulators for:
- 12V (FAN/Light/...)
- 5V (ATmega2560/Logic)
- power input selector for ATmega/logic (stand alone or power from USB)

* easy DISPLAY + SD-CARD connector
- RepRapDiscount SmartController compatible pin header on board

* up to 6 motor driver with easy micro stepping setup (micro switches)
- TRIPLE extruder
- DUAL Z driver and DUAL extruder
- ...

* 5x temperature ADC connectors
- e.g. 3x extruder thermistor + 1x heated bed thermistor + 1x chamber thermistor

* 5x PWM capable power mosfet outputs (3 with voltage selector for MainPower/12V)
- e.g. 3x (MainPower) extruder heater cartridge/power resistor + 1x (12V) fan + 1x (12V) light

* 1x PWM capable power mosfet with extended cooling area for heated bed

* 6x end stop connectors with power supply
- Xmin/Xmax/Ymin/Ymax/Zmin/Zmax
- can be used for mechanical, opto, hall, ... end stops

* screw terminals *and* pin header for easy motor connection
- can be used with existing 4 pin Molex plug on motor cable
- easy to attach cables without plug

* USB connector and pin header
- pin header is useful when mounting in a small box

* Power and ALL unused pins available on EXP-3 feature connector
- +5V and +12V
- 2x ADC
- 2x PWM I/O
- 4x I/O
- I2C

* full JTAG support
- JTAG can be used during full operation (no shared pins)
(easy to develop/debug new or optimized firmware using Atmel Studio)

Since I'm working on building a Rostock Max piece by piece, I went ahead and got the Platinum package. I won't need some of the items that it comes with, but I can always sell those pieces.

I'd like to say that I can give a review when I get it, but since I'm building piece by piece and I'm just getting started, it's going to be a while...

Any joy with the RUMBA?
When on mobile I am brief and may be perceived as an arsl.
