I owned an M4-220 for six years. I loved it and woud like to have another one some day. I paid $16,000, logged just shy of a thousand hours and sold it for $16. The most expensive annual was $875 which included some fabric work. I couldn't touch one now for less than in the $40's.
To me it was an easy airplane to handle compaired to say a cessna 170. On a cool dry morning with around 10 gal fuel it was something to behold. I miss my little red belly money sucker.
