Reconditioned L4

So Im looking to get a L4 that is reconditioned but it only comes with a 1 yr warrenty. Its $634 with a bunch of cleaning supplies that are not super important to me. The current sale of a new unit is $699 w a 3 yr warranty and no extras. Im torn if I need the 3 yr warrenty or save money and just get the reconditioned unit w 1 yr. Thoughts?

I have one senior cat that pees a lot and has now decided after a health episode he will not cover it. I have a 3 yo healthy somewhat skittish cat and will be getting a kitten soon.

TIA
