If you can be bothered to build your bike from classifieds (STW/Pinkbike/RideIO)/ebay rather than buy a complete there’s a lot of options, especially if you have a few bits you can swap from your current bike and upgrade later.
I’ve recently rebuilt my bike and for under £1K sourced an immaculate 09 Turner 5 Spot (with an angleset included), 2010 RS Revs Dual Air forks, brand new 2×10 SLX group with brakes (Merlin). Wheels, saddle, post, pedals, bars and stem off my old bike, but shop around and there are some great deals for these parts too (these include used parts I’ve bought excellent condition Sun Rims on Pro 2’s for c£120, Hope stem £40, HiLo dropper £85 etc plus hunted around for good deals on bars, saddle etc).
