Got the table now I need a good arm and cart combo

So I finally got my first turntable, a Townsend Rock. Now I need to find a tonearm and cartridge. It would be nice to fine a new arm/cart combo.

Please share,
I do have the head shell for the trough. Was thinking it was something different. Why are you moving the hadcock arm?
Years ago I ran a Rock for a while. I removed the trough and ran an Eminent Technology air bearing arm with a Shure V15 Type 5 - actually sounded pretty good. ET's can be had quite cheap if you look.
too many arms, tables and cartridges. It have an etII arm too that is for sale, also a Grace 704
