I'm looking for comments on the OA-4.0 inch reflector offered by DGM Optics. For the price it seems as though this is somewhat pricey for a 4 inch reflector, but I have been told that this scope's performance equals that of the 4" APO's. Then cost wise, does it make more sense to own this scope rather than investing in the more expensive APO's.
