I don't know where you are in Norway, but I have seen some of the cheapest hourly rentals on the newest aircraft in Norway.
E.g. at Jarlsberg (Tønsberg), rental is cheap - an almost new C172SP for 1,200NOK or a Tecnam 2002 for 890 NOK. Instructor at 400 NOK. With today's rate of exchange that is not far off half what you might pay in e.g. the UK. Torp next door is slightly more, but you get upmarket facilities which Jarlsberg does not have. (Although, to be fair, both are pitifully quiet compared to the average UK airfield.)
As mentioned by others, you get what you pay for and solely choosing on price is short sighted. There is also a logic which says you should learn to fly in an environment you will be actually flying in later. Furthermore, you will get to know local people which may make your subsequent transition into actually flying for fun easier w.r.t. finding a group or similar.
Rushing out on a 30 days' 45 hours' course in Spain to then return to Norway and fly every other weekend can be recipe for unhappiness.
Lykke til.
