I too am a refurb evangelist - and here's WHY you should go refurb (these are from various apple verbage on the advantages of their refurbs):
# It performs and looks like new
# You get the same one-year warranty as new
# The computer carries the same eligibility for Apple Care as new
# It is fully tested (including full burn-in testing)
# It is refurbished with replacement parts for any defective modules identified in testing
# It is thoroughly cleaned and inspected
# It is repackaged (including appropriate manuals, cables, new boxes, etc.) nothing is missing
# It includes the operating software originally shipped with the unit and the custom software offered with that system
# It is placed into a final QA inspection prior to being added to sellable refurbished stock
# You get a savings several times that of any coupon or promo code
