There are a number of Maxxum camera's that were cheap/easy models ... like the 3something (lowest end), then the 5something (next up the line).

The 7,8, and 9somethings were targeted at serious photographers (though some of the xi series weren't so hot) ... so I can see some of them being higher in price ... though even the great Maxxum 7 can be found for under $150.00
