Psst....I doubt Cube will like this but:

Also you can make a dual extruder MakerBot Replicator 2.
MakerBot doesn't offer it but it's out there:

Besides you can just a get a knock off with dual extruders:

Another difference between printing PLA and ABS is the temperature of the extruder nozzle.
Note the approximate temperatures for PLA and ABS are listed at the bottom of the last link above.
Also the tolerance of ABS is different. PLA prints tend to change dimension less as they cool.

I own the following 3D printers myself: Up!, a heavily modified SoliDoodle 3 and 7 Prusa printers
The modifications on my SoliDoodle 3: extruder, rear axis drive, SDP-SI cogs (some Fairloc), GT2 belts, VXB linear bearings
I really tore the SoliDoodle software apart to try and increase the quality of things like printed circles.
I am working on putting an all aluminum dual extruder on a Prusa frame (though it might end up a slightly wider Prusa frame).

I agree that during build season a new 3D printer build might not be wise to rely on especially if it's the only printer you have. Luckily most teams will participate in FIRST over years so what might take too long for this season (seeing as it's nearly December) might work out just fine for next year.
