Backpack recommendation

Hi everyone, just wanted some advice on backpacks. I'm looking into some semi ultralight backpacks for hiking in the UK and some small thru hikes in Madeira. I also want it to be relatively tough as I do lots of outdoor climbing and I need it to be able to carry stuff into Crags.

Currently I'm looking at the black diamond beta light 45 as it's roughly in the weight range and has ultra 200x. I've found it for £246 ($325) but was wondering if there was any comparable packs you guys could recommend. Bearing in mind I would have to pay 20% tax on any pack import.

Thanks!
