I like ones that have azimuth adjustability, like this single pin one
look at 'seller's other items', he has many variations, two pins (check your arm's fitting), this one is aluminum/magnesium which is a nice combo for weight/strength.
open sides, I like, but you don't want any flexibility.

search: 'headshell azimuth', sort by price low first, I put in $30 minimum to eliminate headshell or azimuth accessories
