I'm going to recommend you stretch your budget Chris and go for the EM200.
Even if it means you hold off on the FSQ or FS102 for a while.
Believe me it's better to go bigger on the mount first up than having to upgrade later.
Once you start adding on the two scopes plus your DSLR you'll wish you had the load extra capacity.
You may be upgrading your Nikon to a larger model too or you may want to through a good lens on there.
You'll future proof yourself with whatever combo you may want to use later.
If anything, look at getting
the EM200 Jr and add an Argo on it !
Food for thought.
