I also think it's probably better to go with a separate timer and strip. I haven't heard really good things about the combined ones, and they strike me as expensive enough that getting a good quality (metal, perhaps even GFCI) strip, and 2+ timers would probably be cheaper. Plus, then you just have to replace whatever part fails, as opposed to the whole piece if the combo unit fails.
I've had reasonably good results with some dirt-cheap timers. I'm currently on year two of one of those IKEA timers (and I've still got the second lying around here someplace...), and I think I may occasionally loose some time, but it's probably more due to me shutting off the whole powerstrip when I do a waterchange, and forgetting to readjust the timer. Even if that's not the case, it's a small enough change/day that I don't see it as an issue.
