Here's my thought:

It's fairly cheap ($200) and it's Blaupunkt. While Blau might not be the best in the world, they're certainly not going to put something out that's embarrasing. In addition, Crutchfield will accept returns up to 30 days after purchase and pay the return shipping costs.

It looks like it's a good deal, and if it turns out not to work for you, then return it and get something else. Since all the real parts of the Class-T are made by one company, then if you don't like one, you're probably not going to like another, either. In that case, Crutchfield's lack of further Class-T amps is probably not relevant.

I say go for it and then let us know. I might get some of them when I get my new car. I really like the small size and high power efficiency.
