I would never buy a spa from a company that doesn't have a rep in your area. By rep, I mean a dealer who will service your spa. Everything manmade breaks. Buy from a solid dealer with a good product. There are always problems that follow price shopping. On the other hand, don't buy as soon as you come to price. Go home and research if that price is a fair price for you area. For example, dealers are wanting to get some revenue in the winter and get rid rid of 07 spas.
If you are in a cold climate area, you will select a different tub that if you were in FL. Make a list of what is important to you. Insulation, price, dealer/service, looks, features....
Goood luck
