Looking to be buying a projector for my 30th but a bit unsure on what to get

Main worry is will it be for slideshows or movies, ie is the refresh rate high enough for watching films and using for xbox/ps3? Ideally with one of those remote controlled 200" inch screen

Seen a couple, anyone able to give me some pointers on whether they will do the job (despite what page says, always NTE "never trust ebay")

Looking to spend around £200 is it worth it or do you really need around 500 for a decent one
