I used to own an LP330, which is basically an LP335 with a few less features. I used to think the picture was pretty good, the greys were a little washed out and I had to use a grey screen to get a decent black level. The image was very sharp and the unit was very small and portable. The built-in scaler works well on video material but often fails to sync correctly to computer output (using a GeForce 2 GTS). No screen door to speak of, of course. The replacement bulbs for this unit are more expensive than replacement bulbs for the LP340/350, and they're only rated for 1000 hours.
I ended up switching to a Dukane 9000D (JVC G10 DILA equivalent). WOW, what a difference. The only advantage to the LP330 was the smaller image side at the lens works better with my ISCO II anamorphic lens (I get some vignetting with my DILA in my installation).
In conclusion: If you can get one _really_ cheap, and you're not hugely picky, it's a good little projector. But I wouldn't spend more than about $1500 or so on it when there are a lot of better projectors that can be picked up cheaply with better light output, contrast ratio, and ability to sync to computer sources.
Good luck!
