Which interchangeable circular needles should I get?

Hi!

(First post so a bit nervous)

I've recently picked up knitting as an adult after my grandmother taught me as a child. I'm finishing the arm of my first adult jumper and halfway through a jumper for a toddler. l've also finished two jumpers for dogs. I'm really really loving it and can see that this is a hobby I want to continue with for a long time. I've learned so much since the start. To start I got a set of 4mm/40 cm bamboo circular needles from sostrene grene. They were okey, but ultimately I didn't like the bamboo and needed longer ones to got some from Pony, 5.5mm and 4.5mm and 80cm. They're aluminium and less pointy. I like them better but I find it really annoying to magic loop them for smaller circumferences. I think it's time to get an interchangeable set.

I'd really like your advice on which ones would suit me. I have a couple of thoughts but very open to feedback and your suggestions. I think I want metal ones over wood, not that pointy, haven't yet tried ones that swivel but would love that. I would like them to be quite short as I wouldn’t have to use DPNs for smaller projects. I live in London, so would be great if they were available in the UK.

Since I'm quite new I want ones that aren't too expensive but will still work for a while and suit me as a learn and attempt more difficult things.

Any help or advice is very much appreciated, even if it's pointing me towards someone/somewhere to ask this question instead.
