I have no experience with the LeMond trainer. I have a Cycleops Fluid 2 and it's built solid (as in metal parts and heavy) and it's easy to get bike attached and tightening the wheel to the resistance unit is easy and straightforward. I did have a fluid leak from the resistance unit after 2.5 years but they replaced the resistance unit, no questions asked. Never asked for a receipt or date of purchase. A lot of people seem to like the Kinetic Road machine.

No experience with Lemond. But I really like Cycleops Jet Fluid Pro; better than Fluid 2 in my opinion because resistance doesn't change after 10-15 minute warm up like it does with Fluid 2.

I haven't used a LeMond but I seem to recall people saying it's very noisy. That would put me off.

Also, if attaching the bike is a concern, a direct drive trainer might be an issue.
I suppose it depends what you currently find annoying about attaching the bike. With most non-direct drive trainers, like my KK Road Machine, it's just a case of clamping the rear axle in the trainer via the QR Skewer caps, and engaging the resistance unit. Probably takes me 20 seconds without hurrying. I haven't used a direct drive trainer but I'm going it's a little more involved since you have to take of the back wheel and put the chain onto the trainer cassette and clamp the bike in place.
If you use a dedicated trainer wheel and have to switch over from your road wheel each time then a direct drive trainer might be as easy or easier.

I do tend to use a dedicated trainer wheel, but not always. But the problem I have with my 1Up is the tension adjustment. I can't get it tight enough without slipping. Therefore, I install the bike on the trainer with the back tire deflated (tension adjuster preset) and inflate the tire. It works, but I have to inflate the tire every time I install it on the trainer.

Get a Fluid trainer. The Lemond trainer is incredibly noisy. I'm very happy with my Cycleops Fluid 2 trainer. I would shop around and buy a new Fluid trainer rather than buying something that may be on it's last legs. That said my Fluid 2 is going just like new after 4 years of constant use.

The Cycleops Fluid 2 trainer can be had for like $275 brand new right now. From my experience with Saris customer support and what I've read from others, I would feel fairly comfortable buying a used Cycleops trainer.
