Well the price is for 1 projector. A 4 watt module only will cost you 1650 euro excl vat and when buying it from Kvant 1800 euro. So its a fair price imo.
The 3 watt has slightly better beamspecs so the price for the 4 watt is the same as the 3 watt since you have more power but slightly worse beamspecs.
If someone is really shows interest then i usually explain a little bit more what the difference is between the 2.
It,s not nessesary to explain all the details because 95% of PL can,t afford it any way. That is a fact and an experiance from the past couple of years not ranting anyone.
Hobbyists don,t charge money for shows most of the time so they don,t get money in to expand their collection of projectors and doing bigger shows. Brad, you are an exception of course
