Anyone in the UK ordered from these sellers? (Matex/Teqex/...)

I've been looking to buy a sapphire NITRO+ 7900 XT and just trying to price up and work out finances for it. on pcpartpicker it shows the following listed:

- Scan (out of stock)
- Morecoco
- Amazon (reseller)
- Overclockers (out of stock)
- Clove Technology (out of stock)

I did a quick google shopping search for the card and got a few other companies with good prices for the GPU but I am a bit sceptical of them so wondered if anyone had any experience with them at all? Here is the list:

- grooves-inc.co.uk
- networkintegrators.co.uk
- bleepbox.com
- Matek.net
- teqex.co.uk

Thanks for any help
