Just got Logic Express 9 yesterday-and I'm very impressed with the new Varispeed tool and Amp/Pedalboard designer.
The latter is very easy to use-even easier than Amplitube or NI Guitar Rig.
Haven't looked at using Flextime yet, though.
This Apple page for Logic Express 9 mentions "
Warped Effects for Space Designer":

However, I'm pretty sure that Logic Express does not include Space Designer.
I'm very happy to see Apple has added some cool guitar amps and effects for version 9.
KORE Player:
