That's a lot of money just to feed a few cows.
Farm auctions occasionally have them around here that often just need new hoses, wiring, or cylinder seals put in. A lot of people threw them in the corners of the shed or in the fencerow when bale beds became popular. Might ask around some of the older crowd that recently retired or you can just build them or have the local FFA shop give a kid one for a project. They're just a switch, cylinder, pump, solenoid, tubing to get to the ball attachment and heavy angle iron for the rear and mount any old 3pt hay spear to it. Most look like this but covered in rust.
The B&W ez loader is just a better looking package that does the same job. I gave $600 for mine in an online auction a few years ago but I see they're advertised online for some crazy price. Heavy baleage bales will make these older style B&W bar type spikes bend often. I'm going to relplace mine with the better newer spears when I finally break one off.
For 20-30 cows you could even get by with a large pice of angle iron, and old spear, and a cheap 4 wheeler winch to tilt it back.
