Hot tub recommendations?

Hi all. I'm in the market for a hot tub. I live alone, have a secluded yard, and do like to have friends over. I'm thinking a six person tub, but would like input from people who have hot tubs or who know hot tubs. What size do you recommend and what brand and model do you recommend. Why? How has your hot tub worked out for you? Thanks, Tim Aka findinout
