I'll be glad to share what I can. Yes, we're in CS, and yes, we got it from Spa Palace. They've been ok...not too bad, but not real impressive either. Seems like they do all they can to get out of doing warranty work. There have been a few issues with the spa, but overall it's been ok. SP did not mount the ozone generator properly (laid in on the floor instead of mounting it on the wall or a support. A check valve failed and flooded the ozone generator. SP wanted a lot of money for a ho-hum replacement, so I ordered one off the web. I really like the new one (Del Platinum Eclipse) A couple of the jets got stuck in the closed possition, but that may be due to our water - high calcium (we're east of the Springs)
I use the Eco-One system (http://xxx.ecoonespaxxx) so I don't get chems from SP. I either order them online or get them from a place in Manitou Springs. I replaced my dead ozone generator last month, and that along with the Eco-One is all the chems I need. I do use spa shock if there is a high bather load (guests).
I did most if the electrical myself (bought the breaker box, condiut, wire, dug the trench from the house to the pad.) All the electrician did was actually hook up the wire to the main panel and the spa itself. Don't remember who I used, but his price was kinda high for what he did, so I can't really recommend him anyway. Feel free to send a private message if you like.
