I too was doing the research on whether or not to get a canon grip for my XSi, which will fit your T1i, and I eventually settled for the Canon brand, basically because of some of the horror stories about "Grips-Gone-Bad". And after a while I kept hearing about the wheel on third party grips feeling a little weird compared to the wheel on the camera. So on a whim I hit order on my Amazon page and the new Canon grip was at my door in a couple of days. I am not able to critique the third party grips, but as far as my Canon grip, there are NO REGRETS from me. Yes I may have paid about $100 US Dollars for mine, but that was only about 30 more than the Opteka grip I would have spent. The one story that got me hooked on the original Canon Grip, was the on with the battery traces on the third party grips shorting, there is a pic on the web about that, the words SHORTING and my XSI are two words I rather not hear in the same sentence.
