t1i is fine if you're buying it for photos, but it only shoots 720p at 30fps, 20fps at 1080p, which is useless. Canons 720p is average at best, I would never buy a t1i for video because of that reason. So, if you're looking for a video cam, don't get a t1i.
Get a dedicated video camera. You can find used HVX200 kits for a really good price now, they are selling like crazy. The HVX is still a great camera. The cool thing to do now is to buy an HDSLR, which gives you an advantage because you can pickup a kick ass used hvx/hpx setup because everyone is selling them.
Also, the XH-A1 is a great camera. Yes, it shoots tapes and it's HDV, some may call it ancient. Fact is, it's still a good video camera.
Now a days, you can't worry about what you're shooting with. Unless you make a living shooting, you cannot keep up with the trends. At some point you just have to give up on trying to have the latest and greatest gear and create kick ass work with what ya got. It's tough to get that point across to people sometimes, but the sooner you embrace it, the happier you will be.
HPX, HVX, XH-A1, T2i, 7d, HMC150, HV30, Go Pro, many more
They are all great cameras, pick one and go shoot.
