Tonearm advice for a Lenco 75 build


Hi all,

I'm going to build a TT from a Lenco and a PTP plate. I've been considering an Audiomod tonearm, but without being sure of its value against the latest version of the Origin Live Silver (MKIII) or a Zephyr.
The idea, if everything goes according to plan soundwise, is to sell this tonearm and get a Terminator at a later stage.
What would be your advice? What other models should I consider?
Regarding the cartridge, I'm interested in the hype surrounding the modified DL103R but without knowing how it compares with the rest of the market in the same price range (the reviews always assess this cartridge without comparisons). I'm totally open for other cartridges around 700$.
Thank you all for your insight!
