We have been using this part ( for
some time.  It doesn't have the external slot you mentioned but it has
been very reliable for us.  Our experience with DiskOnModule was very
negative, lots of failures.  One word of warning, hot swapping of
CF from the PC engines product is not recommended.  I wonder if the
devices you point at below have this limitation.  If they do, external
access might not be a good thing.
