You could pick up both and sell one, that way the other one doesn't just sit outside and get rained on. :c

Personally I'd take the tray loader, but that's because I already have a slot loader Indigo model. Either way, if you pick both up and it turns out the tray loader doesn't work I'd take it off your hands, I'm actually looking for a fried grape tray loader for one of those "someday" projects.
