I used to, even though I never played. Collected and painted for a bit. All during the 1st edition era. I still have a bunch of painted beaky SMs, IG troops, some Harlequins, and a bunch of Eldar Guardians. Nothing was painted according to existing chapters, races, etc. Just my own tastes at 13 years old. I had an old 1e Land Raider that I sold on Ebay for, like, $100 back in the early 2000s. Still have an old Predator, painted up, that I suppose I could sell, but I figure with the paint, it's less valuable. Got an old Rhino that I heavily modified to the point where it looks like a Chaos SM Rhino, but there's no way anyone would allow it in competition, so it just collects dust.
I've thought over the years abotu looking into the tabletop game, but then I look at the prices for ForgeWorld stuff and I lose all interest.
