Hi Frank. Thought I'd mention that I'm working on a new album and it's being done almost entirely with Colossus. The sounds are simply the most realistic I've come across. I am particularly fond of the Steinway piano sample and the guitars such as the ones you provided a demo for. Very easy to customize sounds too.

The best thing about Colossus is the amazingly low noise floor I am able to get at recording level... it's like -68db which barely registers on the vue meters in Sound Forge. I've tried a lot of different techniques to try to get that low of a signal to noise ratio from hardware synths and can't do it. Definitely the choice for studio use.

I have a friend who bought one of those expanded Receptors outfitted with Colossus and tried to use it on stage... he eventually got frustrated with it and sold it on eBay, saying it really wasn't ready for primetime. Personally I'm just as happy to make backing MP3 tracks for stage at home and use a digital piano live but I suspect one day there will be something like a workable Colossus keyboard or module... all you really need is a 72GB flash memory card...
