Wheres the catch?

[tmcd35]

Just saw this advert on the BETT home page:

 

Home - CASIO Projectors

 

20,000 hours light source life. I make that nigh on 12 years of use. There's got to be a catch, some other replacable consumable part that they'll charge you £300 a year for in lue of the lamp. If not the cheapest I found on the net was $800 (£600?). That's a bargin compared to other projectors.

 

Any how, I think I'll be checking out Casio's stand for more info on Friday!
