We ended up buying the Reward tonight. We went there all prepared to buy the Mirage and again started looking at the Reward. We both knew it's what we really wanted. I offered her $500 less than she previously said and she accepted. I'm very happy with the decision. The Reward has twice the jets, two pumps, constellation light kit, and more room. It will definitely fit 4 comfortable and give us different seat options for the two of us. The bad part now is waiting. We have to wait for the ground to thaw out to pour a pad off the deck. I'm hoping for 4 weeks but I think it might be more like 6 weeks before we get it installed and running.
Thanks for the comments. I'm sure glad I found this forum. I have been reading a lot of threads and it helped me make a more informed buying decision.
