Seems like Vesalia ran out of stock for the first batch of AmigaOS 4.1 and they don't have it right now. AmigaOS 4.1 for Sam is 6.05 Euro cheaper than AmigaOS 4.1 for AmigaOne, and is available for purchase not bundled with SAM, for the one who already bought SAM boards. With the SAM + OS 4.1 bundle, may be the price of AmigaOS 4.1 will go under 100 Euro (All prices I mentioned here are with 19% German VAT).
