So in Sweden for Winexpert kits its around 80 euro for the classic, 110 euro for reserve and 150 euro for the private reserve and limited editions.
I think you made the right decision starting with the classic range. As for differences, if I remember correctly classic has 10kg of fruit juice...
The kits are a good starting point but you get what you pay for. With the cheaper kits you get a lot less concentrate etc and the wines can taste good but they will be very light and lack body and complexity. If you buy more expensive kits you will get more juice concentrate for the same volume...
