What OS are you hoping to use it on ?
I found that some of the Skystar kit will only work up to Windows XP.
Although some later OSs say they use "Chicago" drivers there is a difference in the instruction set (or system calls) which means the later OSs are not compatible.
I guess that is why many sites have ceased supplying the drivers.
The architecture is similar to the Haupauge WinTV Nova S
worth a try but set an install point as it might screw your system.
