Atik Titan for transit photometry

[SvenTaow]

I need a cheap camera for my transit photometry project. I found Atik Titan that is under $1,000. But I'm not sure about it. On forums, there're many discussions that the chip is rather small and it may have issues with anti-blooming technology. Someone suggested the DSLR camera or ST-402ME as better variants, but these are costly. What type of camera will be better for a transit photometry achieveessays thesis project? Perhaps, someone has ever tried to complete one.
