I made a 2x4 version. Eyelets in the ceiling joints to carry the weight during storage, a wooden 'T' that is only used for install/removal.
I'm upgrading the metal hooks to have washers & nuts rather than threading into the wood on the removal 'T' soon, since I have to turn them every use and I know they are fatiguing the wood.
Crank is from a boat trailer.
I like my setup. I'd build my own again. I also think the 'off the shelf' options are actually reasonably price for the engineering that went into them.
I would never use just the hoist to suspend your top after removal. Simple 2x4s, eyelets, chain, and d-rings will get you a secure storage.
You can see some of it here. I can grab more pictures if you'd like for ideas.
