The S49 and S61 have a slightly nicer keybed than the A series, but they're still semi weighted, unfortunately. I think you might be better off saving your money, and continue saving until you can afford a hammer action keyboard. I've never been so inspired, and my productivity as a composer has never been higher. I figured out I was old enough to finance an instrument and I used the money from the Advance 61 to finance a Komplete Kontrol S88, as I was getting back into composing and I wanted a midi keyboard. It didn't lend itself to my creativity, and I ended up selling it about two years ago to to make some extra cash while studying.

Same thing happened, and it got worse because I was practicing piano more as an instrument in general.

Two or three years later I got a great deal on the Akai Advance 61 (which was one that attracted me ages ago) and I convinced myself that the 49 keys got in the way of my creativity and 61 would be better, and semi weighted would be fine cause this keyboard is higher end anyways. About 6 years ago I really wanted a hammer action, and I bought a semi weighted 49 key thinking it'd be fine for me, but I was never quite pleased with it and eventually sold it cause I would find myself avoiding using it and it got in the way of my creativity. If you want a hammer action keybed, I can assure you that you're going to quickly regret buying any semi weighted keyboard and will end up wanting to buy a fully weighted down the line anyways.
