Spin hoist tackle

After much searching of my spares and my buddy's spares I am coming up dry for obtaining a mast pivoting block/cam cleat.
After looking online I see they come in various capacities (198lb-330lb).
Any preferences on brand or style? They all seem to be within $10 of each other.
Sorry of the obscene URLs.

what else ya got a box full of??? :)
boxes of swages, rigging fittings, shackles, stainless rings, chain plates, sta-set adjusters, spinnaker pole end fittings, snap shackles, quick pins, and the list goes on. 20 years of owning a rigging shop and you tend to accumulate an assortment of misc parts.
