2nd hand Lendrums come up very rarely.
Joys and Joy2s do come up 2nd hand.
From which one conclusion you could draw is that most people who get a Lendrum are happy with it and hang onto it.
And/or that Joys/Joy2s are Marmite; people either love 'em or hate 'em. (I love my Joy. So easy to take out and about with me. I don't know that I'd use her much if I didn't go out and about, though.)
If you are in a position to *try* other wheels, I really would *very* strongly urge you to do so before you buy. Or to buy a popular wheel 2nd hand, so you will be able to sell it again if you don't get on with it.
Try a castle wheel, one that's completely upright and one where the flyer is offset to the side. Try a large wheel Saxony. Try double treadle. Try a lefthanded (flyer on the right) wheel. Try a modern wheel with ball bearings that don't need oiling. Try ones where the flyer sticks out into midair, try ones where you can move the flyer into different positions, try double drive...
In other words, work out what you want to *do* and what you *like*, then try a few contenders.
I loved my single treadle Traveller but once I got my lefthanded Traddy I never used the Traveller again, so I sold it.
I can't spin on a double treadle Traveller for very long, I find the table is in the way of my shins.
I've spun on a 24" Ashford Elizabeth and I can see why people love their Lizzies. But for me, it's the Timbertops Leicester. The friend who bought the Lizzie felt the reverse.
I've spun on a Schacht Reeves 30" and it was effortless, smooth, I span baby camel without realising I was spinning something I'd have said I would find difficult. But... my yew Leicester makes my heart sing.
I span on, intending to buy, a lefthanded yew Timbertops Lonsdale. Absolutely loved it - but the legs are too short, I couldn't get my foot as far forward as I want to on the treadle. Apparently later models had longer legs, so I'll have to wait till one of those comes along.
