My choice out of the two would be this one:
http://www.centurion.de/en_int/bikes...ross+Speed+500 ,as my guess is you don't need suspension forks. Swap the tyres to Kenda Small Block Eights in 32mm and you've got yourself a flatbar cyclocross bike.
I personally can't imagine doing 80 KM a day, 4 times a week on a flatbar though. I'd save a bit more and reward yourself with this...
