At 5-inch capacity, the Wallenstein BX52S ($5,150) is roughly $2,000 above the Woodmaxx MX-8500G+ ($2,695) and $2,150 above the Woodland Mills WC68 ($2,999 at 6-inch). The premium pays for: heavier chassis (505 lb vs 375–790 lb), rectangular infeed throat, 25-inch rotor with a 125 lb rotor, and the 5-year warranty. Build quality is the argument; capacity parity is not the argument.
At 7-inch capacity, the BX72S ($6,495) competes with Woodmaxx’s 8-inch hydraulic-feed WM-8H ($4,795) and MX-8800 ($5,495) — but note the feed type difference. If hydraulic feed matters, the Woodmaxx is the better pick. If gravity feed is acceptable and you want the heaviest 7-inch chassis in the category, the BX72S earns its price.
At 10-inch capacity, the BX102S has no direct competitor in the PTO gravity-feed segment. The closest cross-shop is the Woodmaxx MX-9900 (9-inch hydraulic-feed PTO at $6,995) — a smaller chipper on paper but with hydraulic feed. Between the two, the choice is capacity-or-feed-type, not like-for-like.
