The UNI DIN geometry is a distinguishing feature of the SMARTractor only. There are no other protractors providing this tangential curve. If you want your cartridge aligned this way, you have to use the SMARTractor.
Tawa, Write to Yip by 'mint LP @hotmail. com'. You should mention the tonearm , the TT as well the(axact) dimension of the spindle on your TT. The price is about $100.
I have a protractor from Yip, which is great, but i would like to try the Uni Din to see if it is better in any way. Thing is i have no intention of buying a SmartTractor, Someone will soon offer the Uni din by itself for $100 or thereabout.
Tawa, The Mint tractor is made for an specific toneram/ turntable cambo. The Uni Din or other so called 'universal tractors' are average tractors for all purposes. But the difference between spindle dimensions by different turnatables can be considerable. Your hope to find the Uni Din second hand for $100 make no sense to me because for the same money you can get a more pricise tractor for your specific tonearm/turntable combo.
