HP itself actually has two different product numbers, but they are technically identical. I assume the more expensive version is an extra version with an extra price for the Swiss market with a changed product number to disguise the fact that it is ultimately the same product. Probably Digitech imported the cheaper one via parallel import from the EU, or it is sold by an EU dealer via Digitec.
So just buy the cheaper of the two. They are technically identical. This can be checked on the HP site:
