I looked at Jacuzzi, costco tub, coleman, marquis, phoenix, hot springs and tiger river.... Like I said I was sticker shocked at the prices.. parents had a hot tub made high quality even runs on pool filter systyem nice tub had for 20 years one time being fixed the tub is a beast.. nice and big.. did not even cost 5000 to have made his standards.. so to go shopping and looking at 7000 for a decent tub had to make sure on where spending my husband well earned money... came down to dealer rep and how long in business and how treats customers... Always came back to the caldera spa great warrenty and I am sure will love the jets plenty of variety to jump too and love the foot jet systems on this spa... So thats my list of spas and who won for me plus I did talk to word of mouth of owners of spas...
