I think everyone in this forum could see the demand coming a mile away. Demand has spiked mainly because the folks in the HTPC forum using WinTV-HD and HiPix cards need an 8-VSB source.
The two hard to find pieces are the modulators and the D-VHS recorders (although with the HM-DH30000 now available the D-VHS deck problem is going away; that leaves just the modulator).
This time last year I was just getting my HDTV recording rig together; I felt I was entering the hobby very late into the game. Anyone who wants 'the rig' now will pay dearly for it until a more commercial solution is available.
One piece of good news: it appears that the D-VHS tapes we're making now will be forward compatible with D-VHS decks yet to come.
