Equal or better tonearm than Jelco for like amount of money

New, with removable heads hell, and in its price range Jelco was pretty much it

Groovemaster more less  targeted for low compliance designs

New Jelco series was more for modern medium or high compliance designs. Actually there is no substitution of current production with removable headshell. 

Jelco is definitelty NOT for high compliance cartridges, such arms must be 5g mass. Jelco mass is much higher, it’s for mid compliance, with heavier headshell can be used for high-ish compliance cartridges.

Thimas Schick tonearms available in "9 or "12 inch, removable headshells. Modest price.

Maybe i missed that model, classic Jelco 750D series are higher mass, but no one can recall exact mass (15-21g?)
