wtb: pushbutton transfercase, cheap

im looking to see if any one has a cheap working pushbutton transfercase, im fixing my truck in july and i have every thing ready except the transfercase, im not sure if it works, the guy i bought it from said he blew up the tranny so i bought another one of those, but i dont want to dump too much money into it because i might sell it at the end of summer, so does anyone know where i can gat one for cheap that might have it next month, cheap as in, somewhere under 300, no a lot of $ around so maybe not even that, its a lot to ask but i figured its worth a shot, PM me if you got anything or a place in FL i might be able to find one. thanks
