With light wheels and forks the new Scandal would build up into a decent weight XC bike no problem. Yes it’s a few degrees slacker than most XC bikes, but that needn’t be a huge issue, short stem would liven up the steering. I’m not sure why everyone assumes an XC bike must have a 70 degre HA. My Scandal is nearly built, it’s a budget(ish) build but weight should be respectable even so. They were £165 delivered with a headset a few weeks ago. They’ll be on sale again at some point no doubt.
There’s not much else about in a remotely similar price bracket new. Bike Discount usually have some Cube and/or Radon frames, other than that there’s the Kinesis X, but best price online £450. https://www.kinesisbikes.co.uk/Catalogue/Models/Maxlight/X
