Honestly, this sounds like the worst Bullfrog dealer in the world! How can they take the only unique thing about their product, and choose to display the only non-unique thing they sell?!?!
I'd ask that.
But in all seriousness:
1. The X7 and the R7 are very similar. Same mold, same pumps, slightly different controls (which are super simple, and take a bit of time to work with) Quality wise, yes. However, the jets are just drilled in place of the jet packs, so to me, the X series is certainly less refined than other "value" spas that I have wet tested. However, they have other BF features like the frame. Although, the X-series pillows are about 2% softer than the acrylic... X series pillows really dropped the ball, again, that is an opinion.
2. I wouldn't go with a lounger, but that is just me. I slouch in every seat. I'd rather have the space.
3. The above first statement. Also, 45 minutes away... warranty wise, what do they charge to look/fix. Any co-pays? What is their average turn around time? How long have they been a Bullfrog dealer?
4. Circ pump with any Bullfrog is my recommendation.
