Hello @hallthor,
Another Swede – that is not every day one shows up on KL! I agree that there are not so many options here, but we are not completely without shops.
You can get a Prism Quantum from “Fler Bollar i Luften” an HQ Yukon from “Drakjohan” (I bought a HQ Photon (a fighter kite) from him two weeks ago btw) and also from “Skånehobby”. If you want real fancy kites try Sportkitedesign (though it seems like SKD “ is currently taking a break and not taking orders”).
OK, so abroad I have tried: Metropolis Drachen, Drachenmarkt, Bilboquet, Spiderkites, Elliot, Andykites and Kiteworld. I have never been disappointed with the delivered goods.
I’m currently waiting for a delivery after a recent order from Polokites (but custom kite orders tend to take a while compared to something that is already in stock).
I have not tested De Paddestoel, Korvokites, Space Kites, Kitehouse or Feine-Drachen yet (I’m sure I have omitted several shops here unfortunately).
You can also buy used gear/kites from Fractured Axel (For Sale & Wanted) and Drachenforum (Börse).
Funny, kids had the opposite effect on me. With few exceptions I took a 15 year break from kites when the children were small...
Good luck with your return to your hobby!
Added 19th Sept 2021:
I forgot (in addition to Kite-Lab/Thomas Horvath as mentioned by @Bunduki Vlieger) to mention the shop Kitebg. I have not yet tried their services though. Perhaps not a very large stunt kite relevant assortment. On the other hand gokitinggr, (to my understanding) the corresponding Youtube channel, is much varied.
