I personally LOVE my Heritage Rough Rider .22, and it was a steal for $150. Maybe I just lucked out, but it's got the smoothest trigger I could imagine on a revolver, it's very accurate, and it hasn't had a single malfunction with 3,000 rounds through it. Also the Heritage techies get very good reviews (unlike taurus)... not that I've had a problem.
It's true, single sixes are prettier, but I'd also worry more about it if I had one. Also, it's true most heritages are alloy, but so are Ruger MKs and Buckmarks.
Plus you get an extra .22 mag cylinder with most Heritages.
