Meta quest 3, or wait for the steam Frame

I used to own a Quest 2 and enjoyed it, but ended up selling it as I was travelling at the time and figured I could use the money as it wasn't being used.

I'm looking to jump back into VR and was going to buy a Quest 3 (maybe 2nd hand), but am now wondering if I should hold out for the Steam Frame which is looking likely to be releasing Q1. Not knowing the release date, nor the cost doesn't help with making a decision here - ideally I don't want to be spending more than the Quest 3, as I was already debating between that and Quest 3s.

In the UK, all thoughts and opinions are welcome.
