Well I finally went and did it!
A few days ago I ordered the Pentax XW5mm.
I couldn't resist the special price they're selling at the moment through
Adorama in the U.S. Only $280!!!! With the dollar working so well at the moment, it only costs $267.00



The shipping is an extra $60, but that still brings the eyepiece in at only $330. I'm guessing shipping isn't affected by the dollar and is as is, but I don't really care because it's so cheap anyway.
OPT still have them selling for $360 with shipping on top of that (I think from memory when I last bought my XW10 it was $40).
So yaaaaaaaaay I can't wait for it to get here.

Look out tight doubles and the homunculus in Eta Carina- I'm going to get you good!
haha this thread has gone totally full circle now with my original question.
