Granted, I'm not real "up" on all the brands out there, but if you've only found VERY limited information on the brand, how hard will it be to have it serviced while under warranty? Are you a DIY'er, if necessary?
I, personally went for a "big brand" because of the customer satisfaction, very well known name, and the availability of parts/service. Warranty is quality, too...then again, I want NOTHING to do with trying to fix one of these things...I want to soak when I want to soak, if/when there's trouble, I want to have a tech out to repair it YESTERDAY...
If you're looking at it just because it's inexpensive/cheap...be careful....call your local spa stores and ask if they'd fix any problems, and ask what they charge for travel, etc.
Only you will be able to decide if this is right or not....either way, best of luck!
