A Celestron 8-10" (including the new HD models) with the appropriate Hyperstar lens attachment will give you all the benefits of an ASA scope (even faster imaging...f1.8-2) and everything else with also having a dedicated SCT that you can convert back to normal in a few minutes.
A lot cheaper too.
You could even go the whole hog and grab a 14" scope with Hyperstar for less than the price of a smaller ASA scope.
