Aquilus Spas or is there something better?

[Babbles]

We've abandonded the idea of a built in Rockpool type spa as the cost was astronomical so are now looking at the freestanding route, we want quite a simple round one in stone or marble colour thats tasteful looking (not blue, millions of jets, strange seating arrangements etc etc ) We looked at the Aquilus Spa "Nacre" which looks a bit like it would fit the bill, has anyone any experience of a Aquilus Spa and how reliable they are, I don't know much about Spas but I do know that automated water treatment is a good idea but don't know if this model has that (they'ed run out of leaflets) and if it doesn't what do I need to do to maintain it? Or is there something better out there that would meet the bill, the biggest issue is finding a simple design thats of reasonable build quality.
