Thanks all for your (very) quick responses....
Actually as I typed the NET bit and sent it, I though, hmm, hope no one thinks I meant a MS .NET version..!!!

Yes, its a freebie special on the .NET web designer magazine, due to expire in March 2006, so lots of time to try it out etc. That said, what I've seen already makes me think it's an ok product!
Had a rethink about the registration bit, I think I viewed it originally as "register before you could do anything", but I see it's really a pre-order information sheet, so no problem there - I think normally I would have expected to see that at the time of placing the order, not before. I know now it's not an issue.
The "Classic" skin bit - if I change the skin to Legend or Killer and then update site, no page is displayed when you try to view it. Not a problem, but would liek to use mopre white space (that said, there's masses of it..!)
Anyway, again many thanks for your quick reponses and advice.
