I am a fan of the Mitsubishi LT-30 or Pioneer PL-L1000 variants. If you find ones that operate correctly. The only issue I have ever seen with the LT-30 is the tiny arm lift belt inside the tonearm housing. Pain to get to. But both arms use a standard removeable headshell. There are so many others to choose from. I own many! One word of caution. If you are interested in linear tracking because you think they are in anyway superior to pivoted arms. Stay with pivoted arms. Linear
tracking arms bring a whole bag of issues with them. But the fun and cool factors are off the chart!!
