Chris is right on about the difference... a significant performance jump up from the TRV9's single chip to the TRV900's 3 chips. And yes, it produce images darn close in quality to the VX1000. The difference primarily comes from the VX1000 having larger CCD chips.(posted 9209 days ago)If you mail-order the camera and want good sound you might also want to order the Beachtec dual XLR adapter for the TRV900. I've often found that I can negotiate better prices on accessories when I purchase them at the same time as the camera, and an XLR adapter can be a might important addition for some folks. (That's assuming you have or will want to eventually get good external mics for the camera.)
