1996 Jeep Cherokee New Radiator

I have had a slight leak which was apparently antifreeze. In a big blast of steam shootinf out from under the hood, apparently all the fluids are gone.

No hoses appear to be leaking so the general thought is that we need a new radiator. Is that something a shade tree mechanic could tackle for his financially strapped and currently unemployed mother? Is it ok to buy a used radiator if one can be found?
