Once a few old timers start falling off the perch, their wives and kids will sell off the kits, when enough true builders keel over, the prices will drop away.
By then we'll all be too bloody old to have fun building and flying them, so all those beautiful kits will be hoarded in sheds/spare rooms till they are of no use to anyone.
All the young ones want foam and balsa arf crap now.
One day you'll see kits in antique shops.
