For what it's worth, the container class I wrote recently to hold dbf 
rows is along the lines of Chris' suggestion; output is similar to this:

DbfList(97 records)

or, if a description was provided at list creation time:

DbfList(State of Oregon - 97 records)

basically, a short description of what's in the container, instead of 97 
screens of gibberish (even usefull information is gibberish after 97 
screenfulls of it!-)
