Hi LoCz:
I guess I'm confused. I believe you about the prices you quoted. I saw the price for the regulator on Bristol Scuba's website, but I thought that you had posted the link to the website to show one of the places where low prices for the computers you mentioned was "plastered allover the net". I didn't know that they were plastered by email. Sorry, my mistake.
As far as the link that you posted for the UK's Advertising Standards Authority, I'm no authority in international law, but it looks to me like an arbitration board ruled on how Scubapro/Uwatec should advertise in the UK. The ASA seems to be limited to the UK and doesn't seem to have any authority on how Scubapro enforces their warranty restrictions in the UK and certainly not worldwide. You did say you were trying to leave England "for good" didn't you? Let's hope wherever you end up has warranty regulations like the UK.
Now, to assume your attitude (after I've spent a good part of the day trying to help you make an informed decision)- You don't want to listen to my advice, then don't listen to my advice. It makes no difference to me. Maybe someone else will come along and tell you what you want to hear. Good luck.
Merry Christmas LoCz,
Bill
