I just used my brand new Hullwrecker today. Holy Grist, Batman! That sucker works gr-r-r-r-r-r-eat! Ground it at .020 for BIAB, and I had wonderful efficiency. I was expecting OG of 1.058 I got 1.078!!
Look at it this way -- if he doesn't want to keep brewing, you could always offer to buy it off him at a slight discount for wear...
Cheers!
As for what I did to beer today -- my first BIAB all-grain experience went great! Ground and loaded about 13 lbs of mixed grains into the strike water, just a bit high, and the grains took the temps down to 154F. The reflectix wrap kept the water above 150 for the whole hour, and the boil went great (except I never got any large raft of foam on top, not even with the hop additions). However, I did learn a few key things.
1. Start with 8 gallons of water vice 7. Between boil off and the bag, I lost almost 3 gallons.

2. Raise my ladder up another 4 inches so the hanging bag will clear the kettle.

3. Tighten the chuck on the drill -- the drill was spinning on me, and it wore down a bit of the Hullwrecker drive shaft before I figured that out.
The whole process added about 45 minutes to the brewday, a small price to pay for the wort I got out of it.

Cleanup was easy -- the bag emptied cleanly and there were just a few stragglers to rinse out of it.
Oh, and I fixed a small leak in my copper IC, so I'm happy about that, too.
I have just over 4 gallons in the fermenter of my Against The Grain APA. I'll let y'all know how it works out. Initial impressions on the OG sample -- sweet, grainy (Asst Braumeister said "honey-oat Cheerios"). I know that'll ferment out.
