So I've gotten myself into a pinch and wound up getting scammed on a leaking keggle from a HBT member.

Dude sold me a keggle with "little to no cosmetic damage" but ended up sending me a keg with a hole drilled in the bottom that has been badly patched. I paid $95 bucks ($65 + $30 shipping) and now the seller is claiming it was "damaged in shipping" or that I did something to make it leak. (Truth is that I did do something to make it leak...I filled it with water to see how bad of a job he did patching the hole)
In short, I'm out $95 and this guy is perfectly happy keeping my money. So much for homebrewers helping homebrewers.
I'm having trouble finding anyone that welds stainless in my area, so before I go dragging this thing around the countryside I wanted to get some advice from people with experience with stainless.
Here's two overhead shots from the inside of the keggle (these thumbnails should open a larger image):
Here's a couple of shots of the underside repair in detail:
The repair seems to be leaking in several places, but it's difficult to get a shot of the actual cracks in the weld. This picture shows two that can be clearly seen by the naked eye:
So for those of you that have more experience with these, what would you do?

Assuming I can find someone skilled with stainless, how easy is this to fix and assuming I find someone that's "lesser skilled"...how much trouble am I getting myself into here?
Dreading how much more money I might need to sink into this thing and wondering if I should just sell it for scrap. Help!
