I'd take a cue from pretty much every other retail business who does financing. "Low-cost financing available" in some general place, then on each tile just have "(or as low as $X/mo)" or something like that. When I look at it now, it's apparent that the the totals are different between up-front and financed prices, which makes me think I need to break out a calculator, which tells me there's about a 10% finance charge, which then makes me second-thought the purchase in general. K.I.S.S.! ;)
