Hey Nebraska Outlander Mike Eastman did a blog excerpt talking about the Nikon ED 50 spotting scope and he seemed to like it.
Here is the link.

Also in the EHJ #113 they did a huge comparison of spotting scope across 3 different price ranges and the Nikon Prostaff was one of the spotting scopes they reviewed with a overall rating of each spotting scope at the end of the article.
This should really help you out. Also could you please post any information you have found for spotting scopes as I am in the market for one as well and it sounds like we are in a similar price range.
