They look like nice fixtures. However, it also looks like they might only be available from plumbing supply-type places. This could mean that you would spend close to MSRP for the items.
Finally, when I look at fixtures, I tend to look at parts - and if parts will be available in the future. Moen and Kohler, while being about the most popular fixtures, also have plenty of parts out there - should you need to install a new insert or valve for a faucet down the road. When it comes to the brand you are considering, if parts are not available, you might have to have the old shower faucet and assembly removed, a new one installed and part of your shower tiled over. This could easily be a job that costs $800 if you are paying to have it done. $800 is a lot when you consider that replacement "innerds" for a Moen faucet run only about $17.00.
However, if you want a different look, style, or whatever, you tend to have to pay a bit more for that feature.
