What kind of shooting do you plan to do with the O-GPS1 route?
Do you want wide angle or something with Zoom?
I also have decided to get the O-GPS1. Since I am initially interested in wide frame images with some landscape feature. I currently own the Rokinon 14mm F2.8 Manual Lens. Only $300.
Here are a few images I took with just 30 seconds exposure and some post processing in Photoshop.
I cannot wait to see what I can get with the O-GPS1.

Camera:Pentax K5
Mount:Astrotrc TT320
Lens:Ricoh 135/2.8@F4
Stack of 13 210Second exposures with ISO800,total 45min under the light pollution.
K5 did a good performance and it's not worse than my previous camera canon 1100DA for astrophotography.
