I bought a Quest 64gb for half price after Quest 2 preorder. I received both Quest 2 and Quest on the same day. I use Quest 2 exclusively as standalone PCVR right now, and Quest 1 as standalone. Going from Quest 2 to Quest 1, I immediately notice the SDE, but I love it due to its convenience and IPD range.
There will definitely be a market for them. People want to try VR and I know of a lot of people who would rather buy a used headset now rather than wait a while for a new one.

Hi there, there is always a market to sell the original Quest (and most electronics) on eBay--but the prices have moved downward now with the Quest 2 selling for $299. Last I saw, the original Quest went for about $170 on eBay. Just a do a search, do advanced, and search for recent 'sold' items to see what people are getting.
