You might try asking bike shops if they have any old TS2's they could sell you. Many have upgraded to more recent models in the last ten years or so. TBH my shop has two we don't need, but with shipping it's probably not a great deal across the country. The difference between consumer/cheap truing stands and workhorse pro stands (like the Park TS-2 series) is mostly that they are sturdier with less flex, and the caliper arms are a little easier to adjust. Nicer pro stands (the more recent TS-2 series models, the Birzman stand, Var, etc) mostly have quality of life features for working shops--they fit more axle standards, and have clearance to true more kinds of wheels with the tire on, are quicker to swap between thru axle and traditional axles, etc. Extremely nice ones can actually improve accuracy and decrease build time with features like digital or nonlinear dial gauges, like the P&K lie.
