Projector

I am currently researching this trying to make a decision. There is so little up to date info for uk based sewers.  I do not have a dedicated sewing space so need something small and portable.  Any tips on what specs to look for. I have watched Tammy Handmade video on you tube.

This is such a great question and I'm interested to see what others have to say as I'm afraid I have no experience with projectors.
