Melm, some setup tools ARE inherently better than others, IMO. If you don’t want to pay for the best or for anything that might be better than the TTB protractor, that is your right, of course. But do keep an open mind. ( I’m not touting the new WM kit here; I’m just saying sometimes more expensive IS better.) I own the TTB and two other much more expensive protractors. The latter are both far superior to the TTB in terms of the likelihood that you get accurate alignment.
Wally Malewicz's legacy lives on...Wallytractor
Good news...WAM Engineering now making a universal version of the Wallytractor. It has the novel feature of accounting for inner groove diameter variations between older and new records, as stated on their site. Cost is $395, which seems competitive between the Mint LP and Smartractor, considering the feature set. Looking forward to the release of other products.
