Central 4WD used to have them cheaper than they have 'em listed for now.

Used to be you could get it for $15 shipped, but now it's up to $22 for that thin-wall piece. NWOR also carries them, for around the same price after you add shipping. You can try scoring one cheap off Ebay, or just save yourself the hassle and pick one up from Sears when there's a sale going on. Christmas season is coming up, lots of discounts if you can wait that long. Got my 2 1/8" socket from them last year for 25% off, came out to $18.xx.
