Nick is a TAIG distributor, he discounts your order 10%
below is a cut/paste from his quote for my frankenlathe project...
//clip//
1260 $75.00 Carriage and crosslide assembly for regular lathe.
Includes handwheel assembly and toolpost
\\end\\
10% off that is $67.50... not bad if you've priced comparable parts.
He has parts drop-shipped directly to you from TAIG in AZ.
