I bought three of these - goes to 40Kg - dirt cheap and accurate:

It takes 2-3 weeks (Hong Kong). I hooked all three together in series with my bench vise and compared the readings. I decided to stop at 50lbs; they all read within a couple of ounces of each other. If they really go to 88lbs, well, that's awesome for a $4 investment.
I figure these will help me weigh the various pieces of my plane during construction, even the engine (hang the engine in two places with a scale on each hook, then combine the readings).

PhilImpressive! - but I hope you put on a safety strap, lest this $4 scale comes apart when the engine is on it --

That black strap on top of the scale, amazingly, supported 50lbs in my simple test; I have no doubt it could support 88lbs. And yes, weighing an engine would involve hanging the scales on some kind of yoke above the engine (that's resting comfortably on the floor) and lowering it down to the engine to hook it up, and then slowly pulling up on the scales, not lifting the engine and hanging it on the scales.
