Hi, looking at getting some new alloys for my Astra, what’s the best recommendation for alloys?

Personal choice I suppose but would avoid any 'cheap' alloys as tend to crack easily

Mmmm, cracked alloys, I can verify that one. Please make sure that if you get secondhand to check they've not been welded. My Astra had a welded alloy on when i bought the car. After a couple of months I noticed it was cracking near the bolt holes. That wheel was removed and scrapped. Replacement found on ebay for £15.
