We're at a point now, however, where there have been some compromises as well as some ingenious solutions. And they didn't come from the lamp manufacturers, either. No, the projector manufacturers got smart and have come up with:
Color temperature menus: these allow you to pick a Normal, High Bright and "Cinema" mode. Really, these allow for normal (no changes), High Bright (blue-ish but maximum white levels) and "Cinema" (where the brightness is decreased, the black levels dropped and the color saturation (particularly red) is increased.) It's artificial, but it can work pretty
well.
"Eco" mode – sometimes called "lamp saver" mode: By reducing the power supply's draw, the lamp is effectively reduced to between 60%-70% of max brightness, but you usually get a lamp life increase of nearly 50%.
Dual and Quad lamp assemblies: Some manufacturers are getting really bright projectors because they're using between two and four lamps in combination. The flipside of this is that by using half of the lamps, you can double the lamp life (you really only use half at a time). At least one manufacturer, Barco, has a projector that keeps track of the hours used per lamp and will use the lamp that has the least hours on it, alternating throughout the life of the lamps.
As to the price of the lamps, well, you're really out of luck there. You will spend between $375 and (on the 10,000 lumen projectors) up to $5,000. As an average, though, the vast majority of lamps will cost $500. It's that old supply-and-demand thing.
As a side note, Philips had a lamp factory burn to the ground a couple of years ago and it caused a real shortage for several manufacturers' products. Ushio, in particular, really stepped up their production and broadened their lamp "family" to become the second largest lamp manufacturer in the world (behind GE, and that includes light bulbs, too). The lesson here is to stock up on at least one spare lamp for every two projectors you own (assuming identical projectors).
