I recently purchased a Z3, and I think it's a fantastic piece of kit, and I paid £998 with one bulb!
For £848 inc. spare bulb from Ivojo you really can't go wrong. It really is the best buy projector at the moment.
The Ae700 is a good projector, but even at £999 (one bulb) from Discount Electrical it really doesnt compare to the Z3 for value, especially considering the other benefits that the Z3 provides, e.g. dust blob removal, extra component input, 3 year warranty, no
VB, very quiet operation....
