It's rather steep price, but you get what you pay for.
I bought Version 6, there are free updates as long as they work on that version, Version 6 is now almost bugfree.
When the released version 8 (they skipped 7
) There was an upgrade fee. But Version 8 is a lightyear bigger / faster and better than Version 6. Think about it, if Windows2000 was almost bugfree, you wouldnt expect to get WinXP for free now would you? No, you get servicepacks. As long as the company works on your Version of the program you get free servicepacks.
And, Version 8 is really good. The prefs is so big you can get lost (but you dont need to, it works right out of the box), there are addons (free, made by other people like Mouser
You should really download it. It works in 30days with everything working. If I remember correct you can get another month by sending a mail or something.
And, no, I don't work for them, I am just an old Amiga-dude who likes software the programmers care about...
And remember... its Australian Pound... Not English Pound...
