oho.. you have made me a traitor.
1)First of all do you know anyThing on projectors ?
2)china brand: Have you heard about
luxeon?? out of 2 links 1 was for
luxeon if not this link will educate you [no offense but i had to mention here]
Luxeon Projectors: Luxeon L713V 3 LCD projector
china products are NOT damn cheap !see here it reveals that you need 'knowledge soup' for av products!!!

, may be your mini ideas are parts of El-cheapo china stuff sold in india [personally i dont buy these except LEd light]
Products like "Shanling CD-T100se" are really admired but many cant afford to keep one
3) price and recommendation :
ok here your noob research will show up
a) ebay guy selling
Luxeon which has better brightness than Dell m110
tell me a better projector in 25k with LEd light ,get a better branded projector in that price and same specs you will become star
b) the bigger speaker in Luxeon help people for small videos like family videos , talk shows ,my dell has too small irritating
speaker
4)ASk google baba what is XGA what is WXGA?
i myself use 110 inch screen and happy that supported 200 inch wide screen needs that extra pixels, the 720p also in in XGA...ufff
5)ok end of class , now i had to frankly say why i cant give the link
my research gave me great deal ,same link some of my friends use for business.
So obviously... not for public service
