Home projector - horizontal keystone?

I'm looking for a budget projector for watching occasional films at home. Don't have/don't want a TV, but have a suitable white wall with a shelf opposite so the projector should be reasonably inconspicuous. Problem is the shelf is slightly offset from the centre of the wall, so I believe I need 'horizontal keystone' to correct this. Having a lot of trouble finding any budget (<£400) projectors which offer this. In fact only one so far which doesn't seem to be available in the UK. The throw ratio needs to be about 2 which also narrows down the options - most seem to be much shorter throw. Does anyone have any suggestions for something with similar specs?

Cheers!
