I'm quite happy with a 62º AFOV so these seem quite attractive.
However, Bintel has them listed for pre-order with a price of $379 which puts me off a bit (and is double the price of a used Radian).

Perhaps someone more adept on IT than me can find the original post by "ausastronomer" (John Bambury) who undertook a very thorough review of the Radian alongside a whole bunch of other eyepieces including the Pentax XW - the results were surprising and his conclusion was that the XW was overall only better by a slim margin. On some other individual characteristics the Radian was better.
Bottom line - he considered the Radian to be no slouch and an excellent EP well worth having.
