I think you're right, Dennis.. the DMK21F04 has dropped to US$290.00.
The only difference I can see between the 21F04 and 21Af04, is that the "A" version can do 60fps while the 21F04 can only do 30fps.
Can't believe it though, my version the "A" version, cost US$490 only a few months ago, and it was 30fps - upgradable to 60fps via a firmware patch which I haven't done yet.
So US$290 is a bargain.
The 60fps is good for the moon and sun, but no good on the planets unless you had a 25" telescope
