Resolved Any way to boot up in "Target OS mode" every time I turn on my Mac?

Is there anyway that, when I turn on my iMac, Macbook Air, etc., that it lands me in the "Target OS mode" that let's you choose Mac OS X or Windows 7 (for bootcamp) every time you boot up WITHOUT HOLDING ON THE OPTION KEY? Because sometimes my keyboard takes a while to "boot up" so.. any I don't wanna have to go to system prefs just to make sure I get into the right OS on next reboot. Thanks.

 

Thanks for the great+concise replies, guys. I'll take a look at both. rEFit is awesome, as I've had some experience with it before (dang, just can't remember where I've used it before), and BootPicker as well (seen it in those old iMacs sitting in universities). Thanks again, and will pick something to use
