If you look online, PC's can still be had for around $110. And the UDM's,
G110, and Griot's are all company affiliated with the price ranging from $130-$180 depending on where you shop. FWIW, I'd bet you could come across a gently used one of any of them for around $100. Also, I have found the 3401 for about $270.
It's just suprising that with all of the competition between the orbitals that you don't have the same with DA's. Nice find on the Makita BTW.
