I'm finding there are quite a few Milwaukee 1675 and 1680 Hole Hawgs listed on eBay that haven't received many bids. Some are claimed to be new in the box. You may want to check them out. Be sure to review seller's feedback and terms before bidding. Good luck if you happen to be wanting one.
To find them search as follows: Milwaukee 1675 or Milwaukee 1680 or Milwaukee Hole Hawg. Please note that the 1680 is the beast Super Hawg. Another pretty nice heavy duty right angle drill is the Dewalt DW124 and DW124K. The K means it comes with a case.
Note: I, Woussko am not selling any of them as of this time, and I do not personally know anything about the sellers. Bid at your own risk.
