Radiator repair

I got home from a drive yesterday and there was a puddle forming under the van. It was not over heating, the top and bottom hoses were interact, then I saw coolant coming out of the radiator about half way up, about an inch in from the passenger side.
I have replaced radiators, but never dealt with repairing one. Are there any repair options that are worth half a damn short of having it rebuilt?
If I do need to replace it, are there any new radiators out there to be had, or is it a matter of custom built or finding a serviceable used one?
Thanks for any info anyone may have!

Here's a thread on the subject that might prove useful to you. Hope it helps!
If you read the input from members and scroll down where there is a link to a Champion radiator that fits these vans.

Let us know if this works out for you!

Well,,,,,if you want to stop the leak,,,,,the tube is like a straw connecting the top and bottom tanks,,,,,coolant flows down from the top tank through  each tube,,,,so if one or more are leaking, you can rip off the fins around it, find the hole solder it or cut it and bend each shut then solder them,,,,radiator aint going to care if a couple of tubes are missing or blocked off,,,,a radiator pressure tester or pumping a few pounds of air into the overflow fitting will force the coolant out to find where its leaking,,,,,you can have the radiator recored where they solder your tanks on a new core or find something to make work,,,,,so you got choices,,,,

Thank you guys very much! That champion item looks promising. The van is not driveable right now anyway, so I think I will pull the radiator to inspect the damage on the bench, and go from there. Hopefully repair is an option, but it's nice to see that this might not turn into a $500 endeavour.
