I own a 10ht and have only read about the lt150 so take my feedback for what it is worth.
Sony 10ht native 16:9, no large black bars or special lenses required whereas the lt150 is 4:3. You will have more pixels working for you on a native 16:9 projector than a 4:3. If you were to purchase a panamorph lens to achieve 16:9 you would also require a video processor that can scale the picture appropriately, this could add a couple of extra grand into your lt150 configuration. If you move between 4:3 and 16:9 material you will need to move the lt150 forward or backwards to matain constant height. On the 10ht 4:3 and 16:9 will be the same height, the projector will just put black bars on the left and right on 4:3 material.
The 10ht Has a zoom lens, where the lt150 does not. This means for fine picture size adjustment you just have to set the zoom, whereas on the lt150 you will need to move the projector.
I believe that the 10ht is a quieter unit, please review the specs to confirm. I know I have read a lot of posts regarding the requirement for a hush box on the lt150. You will not require a hush box for the 10ht.
10ht will have a large screendoor than the lt150. You will need to assess if this is a problem for you. Many people can not see the effect once you are a few feet away from the screen.
Rainbows, 1 chip dlps have them lcds do not. You will need to determine how critical this issues is for yourself and your audience.
Both technology types can suffer from dead pixels and it is debatable what the life span of each technology type is. As far as moving parts go I think the 10ht would have less as there is only a fan, whereas the lt150 would have a fan and a color wheel. one could postulate that less moving parts are better but there are a lot of other variables involved.
The 10ht for the most part is like working with a 16:9 TV sans the tuner. It has standard RCA inputs for RGB and Component inputs. I think you will need to purchase a breakout cable for the lt150.
A lot of folks will say the black level on the 10ht could use improvement and out of the box I would agree. There is a very active user community surrounding the 10ht and a process using red color correction filters has been developed which improves blacks and contrast. It would be interesting to compare an improved 10ht to some of the other dlp/dila projectors. FYI a color correction filter is ~25$ at a good camara store.
It looks like the lt150 will be a less expensive projector, according to posts it looks like the price is around $2500 where the 10ht is $4000+ or so.
The lt150 looks more portable the 10ht while movable it was not designed to be placed in a carrying bag and moved around.
I dont know if the lt150 has a digitial zoom feature or not. The 10ht has a zoom mode designed to be used with letterbox 4:3 dvd's or tv soruces. This is very useful as it will allow you to utilize the entire 16:9 screen. This might not be an issue with the lt150 as it is a native 4:3 projector.

IMO, I realy enjoy having native 16:9, based on my experience with this projector and trying out 4:3 office projectors I would never purchace a 4:3 projector for home use. I hope to see more 16:9 dlps and dilas out there in the future.
Good luck on your choice and if you have any further question on my 10ht please send me a PM.
