I contacted a few people that in my opinion had fantastic photos (including regric -last month's POTM winner) to inquire what kind of glass they had and all of them had regular -not starphire- glass.
My main concern was really how clear it would be in pictures since I'd like to get more into photography (again - I still have my old Minolta film camera on my desk right now. lol) With that out of the way the difference between a stock tank with regular glass and a custom tank with starphire (since I just want a regular stock size) doesn't seem to justify the upgrade in my case.
In fact I might squeeze out a nice starter kit on a camera with the savings.
