Haha, have you ever used an XHA1?  It's such a huge step up from an HV30.  HV30 is a great camera, but don't forget it's still a consumer camera.  XHA1 lets you control everything about the image.  HV30 doesn't even have full manuel without some awkward workaround.
As for it's competitors, obviously the HVX200 has a few features that the Canon lacks, but it costs easily twice as much if you factor in P2 cards ect.  XHA1 destroys the FX1 because of xlr inputs, advanced color control, better 24fps mode, ect.
As of a week ago-ish, the XHA1 was the best camera you could buy for the money.  Now that the HMC150 is out, obviously things have changed.....
