Seriously, just install smarty and do it yourself. Then somebody can always do a basic edit to the templates and you don't have to weight the merits of the 10000X different frameworks against eachother and get back to Making Money!
Although tables is easier than CSS, most browsers will render CSS almost the same way. But not always true for tables. Especially wider sites that need to shrink to fit a screen. I just weigh amount of work I have to do against how much I'm getting paid and do which ever way I feel comfortable with.
