ive been using a 49 key midi to learn for my first 3 months and im now planning on getting a keyboard. the kurzweil KP-80 looks really nice and has everything i need, but it only has 61 keys. i dont want to waste money and/or have less features if those extra keys are just going to be collecting dust (my budget is ~£400)

and as for my intentions: i am just playing (self taught) as a hobby. i dont really care what im playing but im really interested in learning music theory in the somewhat future.

thanks for reading and forgive my ignorance.

edit: decided on getting an 88 key as i think it will suit me better. thanks for all the help!

I'd like it to be portable and light. I don't want any speakers on it for that reason. semi-weighted would be ideal but just regular might be ok also. I'd really like a good selection of patches, It doesn't need to be a huge selection, but something decent to sort of cover all the bases, so that whatever song I need to do, I'll have something I can use. An easy to navigate patch system would also be key. I want to use it primarily for gigging, and I'd like to be able to come up with comparable patches to whatever I'd need to cover. It doesn't need to be perfect, but close enough to fit it well.

If it also works well as a midi controller, that could be interesting, but is really far from a priority. The main thing is a stage piano. Also I'd like for it to be as cheap as possible. I'm not looking for the best. I don't need the best sounds, or way too many sounds. I just need a decent library that can suffice for doing cover songs of basically any style and era.

Any ideas or suggestions would be great!
