Dean I have one of those LP 3mm and also a 3mm radian and you are right these are a very good high power eyepiece only a shade behind the TV in all ways .
I to like its 20mm eye relief , just like the Radian .
I have since fitted a polarising filter to my LP 3mm and its now my high power solar eyepiece when viewing the sun in either of my refractors with my Lunt Hershell wedge and its awesome for that .
The only problem I can see with these LP's , Orion and WO's is that the QC is not as good as TV's and the chances of getting a dud are slightly higher , but Bintel and Andrews along with others will exchange no 'Q's' asked .
Good luck with your search Peter , and sorry mate my Radians are not for sale either .
love them to much .
Brian.

I have since bought the Nagler 3-6 zoom and retired the Long Perng: it is on my desk staring accusingly at me as I type this...
I am very happy with the Nagler: unlike the comment from JohnB I have noticed no off-axis drop off, and the 3-6 zoom is wonderful. It does have shorter eye-relief though.
If you want, I am happy to sell you the Long Perng  : say $40 + postage (it was $99 when I bought it, but Andrews have dropped their price). Drop me a pm if you are interested.
All the best,
