ABS requires a heated build chamber. You can achieve this with a simple homemade hood and a (preferably see-through) cover for the front. Basically you need to block anything that can cause a draft. Then let the bed heat up to 95° for 10-15 minutes before starting the print to heat up the chamber. Fine tune this to suit your enviroment.

Do not heat your HBP above 105°
Slurry works best for ABS

I personally that ABS gives a better part than PLA. At CA's recommendation I have been using PLA exclusively and the results are mixed. I really should sort out my cooling but that's a different story.
