I know this'll be a long shot, but if anyone has either of these for sale, I'd love to buy them.
Astrotrac: Specifically looking for the full basic kit, even better if it has the geared wedge. Don't want the big-ass stand, though, my tripod works fine.
Race ramps: Specifically looking for 56" or 67" ones, even better if two-piece. Also wouldn't mind wheel cribs.
Not really looking for any alternatives unless they're similarly high quality. Not worried about cheaper ones.
