Replacement for another discontinued primer

[gotmyknickersinatwist]

I was using The Ordinary High-Adherence Silicone Primer for ages after seeing it recommended here, since Nip+Fab discontinued their Viper Venom Fix Blurring shot (which I also started using after seeing it recommended on MN).

The Ordinary have bloody well discontinued it too!

I've tried a couple of others but they've been disappointing, including a Rimmel one.
The Ordinary and Nip+Fab ones were both fairly cheap (£6 - £8) and I used them without make up most of the time, as they had that slightly blurring mattifying effect I was after.

Any recommendations for something which fits the brief, please?

I'm using the Charlotte Tilbury Factor 50 primer at the moment and loving it BUT it's the first primer I've used so I don't have much to compare it to. It does make my skin look good though, and my pores almost disappear...

It's a bit out of my price range but thank you for the reply!
