We brought the Lay-z-spa Series 2 last year from drinkstuff.com. I can honestly say it is the best purchase I have ever made and definately value for money. We have had no problems with ours at all and it has brought hours and hours of fun and relaxation for the adults. The spa is cost effective, that you could purchase 7 for the cost of a hard shell one. Being inflatable you can jump around, swirl like a washing machine (the kids love doing that!) and you not banging your knees or injuring yourself because it rubber!
I would definatley recommend anyone from buying one of these. Like with most things I'm sure there are people out there that would not appreciate it or not see the value for money - but hey - one person's love is another persons hate - but I have to say we LOVE IT!!!
