I just use the regular cheapy powerbars.. they work just as good. There are all sorts of fancy types you can get though. The powerbars with largly spaced outlets are great for bulky timers. Sometimes you can only get two timers on a 6 plug powerbar.
I have been using this one for awhile and would definatly reccomend it, if you are looking for some mixed current:
