thats a leading question but here goes
projectors will in my opinion produce an image detail wise as good as the 1080p panels we have today, but the room itself in any projector based home cinema has to play one of the biggest parts in what you will eventually see on your screen.
This seems to be not talked about by quite a lot of retailers and I think it should be, having a demonstration in a retailers dedicated treated cinema room and comparing it to your front room and not telling the client how different it will be at home isn`t really playing ball.
Anyone who mounts a projector in his front room, bed room or where ever which is prominently a white /light decdorated room with a white/light ceiling is not going the get the best image possible out of the projector, infact i`d say its going to look washed out with grey blacks and poor colour and thats even with all the rooms points of light entry such as windows and skylights blacked out.
The room itself will light up from light reflected mainly from the ceiling, back into the room from the screen and this inturn will wash out the image resulting in poor image contrast to say the least. Thats not to say you can`t have a projector at home and not enjoy it, as there is nothing like "the big screen feeling" to put a smile on your face.
There is a screen manufacturer out their who has developed a material which greatly overcomes the negative effect of light bright rooms and what it causes, but it comes at a price. Your money and if you`re allowed to do it by her indoors, is much better spent on "treating the room" and will result in a far superior image.
I have treated my room and to be honest it was like i`d changed my pj to the top model in terms of better blacks and more natural colour, image contrast improve 100% and I`d finally achieved what I wanted which was an image as good or if not better to me anyway my 1080p plasma/LCD images on my panels around the house.
That said not everyone can have a dedicated light controlled treated room, but as said their is now an option open to you with the new screen technology, but I thought it only fair to point out just how much the right projector in the wrong room will never be at its best, ever.
Try to get a demonstration of a good setup and see for yourself if you will satisfied with what you see, do this in the right room and I know you will be, in the wrong room you will or should have reservations. But don`t let this put you off, as it will be your room at home thats going to be the most important one and how you treat it to your best advantage when viewing projected images.
your initial question of "how much", I`m thinking of a £1300 projector that should equally produce an image as your panel does, but only in the right conditions, fail to do this and yes it will be bigger, maybe much bigger, but not as good regards image contrast and colour detail. Done right, you`ll never go back to a plasma again as they can`t give you that big smile across your face that a 120" diagonal screen does.
I hope I haven`t put you off as its a great experience having your very own Home Cinema
