Mr Entertainer are essentially SBI tracks (same as Sunfly, Abraxa, Aaron Ardvark even some Zoom). Mostly good with occasional flubs (like any brand). Zoom is great too.
Here is a search database that will give results from several manufacturers including SBI, Karaoke Version, Sunfly (UK only), Zoom (UK only), Digitraxx, Party Tyme, All Star even the latest Sound Choice (for whatever that\'s worth these days) (with direct links to their sites to purchase)pretty much anything in the search results are going to be worth using for the most part (again, all brands have their flubs).
