If we're comparing Powermatic to Oneway, we need to compare apples to apples. The 3520B is not a fair compare both from the size, width, feature, cost and target audience. For that the 4224 is the proper lathe since it has quite similar feature as the 2436, both has 3HP, weight is about the same, the price rage is similar, both have fixed headstock and both are targeting professionals wood-turners. However, the 2436 is by far more massive as the bearings are among the best in their class. The 2436 is for professionals who makes turning their living, not a weekend (if I'm lucky) hobbyist like myself, but that's quite an attractive opportunity
Tucson AZ is a bit too far from here, around two hours flight so I will pass
