P3A price

Now that I bought the mini 2 I’ve been thinking of selling the P3A.
It has the hdmi module so I can connect my avegant glyph goggles.
Has 2 batteries.
One leg i had to do a minor repair when I bought it.
Never been updated.
I see refurb ones on ebay for $950 and other for $1150
I don’t see that kind of price even with my goggles
I was thinking $500 for everything?
