Sumiko Blackbird

Need some opinions plus some practical advice here. Does this cartridge seem to fit the bill of "last cartridge you'll ever need" for someone who's likely to remain on a "moderate" budget from here on out? Is there any type of music that it prefers? Now for the practical......could the Blackbird be used on a Music Hall MMF 5 until, say, money for a Scoutmaster or mid line Nottingham came around? Thanks...
