I don't think $150 is unreasonable for that setup at all. Most Singer cabinets I see are either oak or walnut. That one is birds-eye maple and the most ornate style short of a parlor cabinet. The pheasant decals are in nice shape too. I'm wondering where the powder blue motor, controller and light came from.
I really like the National up in Port Orchard too. The deco trim is nice. I really hate hidden reserve auctions though. If there's a minimum price you want start the bidding from there so people know if they want to bother with it.
