Ideas for a young 8 year old- useful/ long lasting main gift

[Alakazam7]

I know what to get for things she'd like and stocking fillers etc but am struggling for a main present for her. She already has a TV, iPad and computer (which Weren't from me) and loves technology and likes make up/dressing up and music. Any suggestions for a gift maybe around £100 but over if it's going to last. I have no experience of buying someone's main Christmas present so would appreciate advice.
Thanks

Trampoline?

Is a possibility, the only thing that puts me off that would be is it better to wait until summer for that, she has a summer bday.

Yeah maybe then, although our DC got theirs for Christmas and were on it on Boxing Day! It's had a lot of use for 5 years and counting!

Great thanks- will have a look at some!

Karaoke machine? Second hand games console with a just dance/ sing bundle?
