All the basic inputs are there and there is little to know source you won't be able to project. The only thing this projector is missing is the USB presenting via a compact flash card that so many projectors in this class have. It is however networkable via its RJ45 input so that is one area where it still competes.
All in all the Sony VPL-TX7 doesn't offer a lot special features, but it is a good value depending on how plan to use it and what type of ceiling mount you purchase. Maintenance also is going to be a little more time consuming if you don't also purchase the ceiling mount from Sony. It appears, from the image they provide that the mount does not obstruct the filter or lamp door(verify before purchase). Universal mounts however would most surely cover the lamp door. Keep this in mind if you plan to ceiling mount. Your maintenance costs could outweigh any value you got out of buying a low priced projector.
Below are some basic specs. In the next section we will take a little closer look at the projectors physical characteristics.
