I use kickstart and am facing the same problem with my variations I come to 10000. I use Commerce Product option with commerce price attributes Commerce Product Attributes unfortunately it is not a good idea because it is very difficult without new to code it to get reasonable.
Version 2 is good but unfortunately not compatible with commerce price attributes. So now I have the video looked at me and after construction. What I unfortunately not yet looks like here it does not update the price on the product page that is possible with commerce price attributes.
Next I have problems. VAT be shown separately in the price display and on the invoice. I have tried with no success rules, or rather not found the right way. The award-field created in the Taxonomy immediate the price with VAT exemption on. So it should just be there are not 19% but something else. When I get out of the vat expect from the price and so text box that comes back out something else.
€ 72.90 x 19% = 90 € VAT which may never come out here. I know not as yet why.
Next is the problem that must when in the other country wants to send out the vat are expected. I now set shop everything works only if the video after work I do not work the new fields from the tanxonomy it.
Commerce I really like, but it is not to code for an amateur hardly possible to find the right way.
Sorry for my bad english!!
