Choosing a rotary cutter (paper cutter)

[Izlude]

Hi all. I stumbled upon some epson inkjet (not solvent) photo paper in 24" rolls at the thrift. I took a chance and nabbed them ($15). I was browsing the web on ways to cut them for use on a standard printer (making 13x19 sheets and using the scrap for smaller projects) someone assembled pvc pipes as a holder and then sliced them in the rotary cutter as shown. Browsing some of the cutters on amazon, they're around $350 for the higher quality ones. Cheapest I could find was a brand called fangling, there are multiple sellers, lowest being $50, highest $127 (apparently they're the same model, not used or open box) not sure why the price difference. Think I can get away with using the $50 deal just to cut these sheets? Or is the more expensive one a must?
