Default Coronado PST w/T-Max vs SM 40 scope

I've posted this same question in the Astromart Coronado forum, but there's been
no response. Anyway...

I'm looking at a choice between the PST/T-Max combo ($1300) vs the SM 40 scope
($1700). It appears to me that the PST/T-Max has a narrower bandpass (= better)
than the stock SM 40. Has anyone done this comparison? What's the downside of
the PST/T-Max combo compared to the standard SM40?

The T-Max on the PST is reported to block the integrated solar finder
unless Coronado has made some recent changes.

A downside is that the narrower bandpass results in a dimmer image
with only 40mm aperture.

The PST also has very limited focuser range. This becomes an issue if
you want to take photographs or use a binoviewer. Of course, for the
price difference you can afford some adapters.

Later,
