Hmm, yeah, I think that's where I got mine as well. There are a ton of plans floating around on the web; the ones I used, which I can't currently locate, essentially have you build a big box (depending on the size of your walls, maybe 4x6 feet, as it's easiest to use multiples of the 2x4' fiberglass pieces) ~ 6" deep out of plywood (that is, plywood on the "skinny" sides, so the 4x6 foot faces are open). Staple chickenwire on one of the open sides. Load in your compressed fiberglass, and then staple chickenwire on the other open side to hold it all in place. Cover with a loose-weave burlap (or you can go with a tighter weave, like maybe those t-shirt-fabric bedsheets, and then do burlap over that, if you're worried about little fiberglass particles floating around). Screw some diagonals on the back to keep it from flopping around, and then hang the whole thing on the wall.

I have 3 of these on the walls, plus I wound up sewing the excess fiberglass boards into big fabric bags & then suspending them from the ceiling. Our room wound up deader than one might like, but that's primarily because it's so small that I can't afford to have it any live-er than it is. Either way, I didn't spend much money at all on the whole project, so you can always buy/build as much or more than you need & then not use some of it.

The other thing I built that I use all the time & really like are some small-ish (maybe 3'x4') floorstanding dividers. I got some 1x2s, some quarter-round molding, some sheetrock, some more chickenwire, some regular pink-stuff fiberglass, and some fabric. I built frames out of the 1x2s, nailed in quarter-round on all four inner faces so that the round side faces out & the flat is about 1/3rd of the way in. Lay in a sheet of sheetrock cut to fit the frame, then nail in more quarter-round to hold it securely in place. Lay some pink-stuff fiberglass down and then staple chickenwire across it to hold it in place. Cover the whole thing with fabric. Before I assembled mine I also cut some 1x2 "feet" and bolted them on 2 of the faces so that I can stand them up longway or tall-way.

These work great for just-enough-isolation to keep one amp from bleeding into another's mic. The sheetrock is dense enough to stop the mids, and the fiberglass knocks down the highs. And they're small/thin enough that I can slide them behind some furniture when they're not in use.

Of course, if you don't intend to ever record more than one instrument at a time, they'd be less useful.

Does anyone local sell baffling for, say, home recording? Or is there a better way?

Specialty Products on Sunrise Ave. in Raleigh has the Manville equivalent to the Corning 703 rigid fiberglass, if you're building anything.
I got 2' x 4' pieces from there at about $8 /sheet.
