Seriously, with a nice net connection you can setup another (not compressed) chroot with debootstrap in a matter of minutes for testing stuff.
One thing I like about pbuilder is that changes you make while in the shell are effectively discarded upon exit. With the persistent environment Colin describes, it seems easy for the cleanroom to get dirty.
