Smooth make a well regarded elliptical with the flywheel in back - a good geometry. There's no wheels or deck - but there are weight bearing hinges - a cause for concern.

Schwinn's popular 418. A good pick for lighter weight individuals.

Phenomenal advance - amazing geometry puts two smaller flywheels at the side, allowing for a much more compact unit - also lower to the ground - for spaces with lower ceilings. This is the beefier commercial unit.

Another example of the awesome side-flywheel geometry. 21" stride and 300' weight capacity. Very space efficient and low height tolerant.

Tunturi's popular C35. Same hinge issue as the Smooth ellipticals. Short stride.

Ok - the Gazelle isn't an elliptical trainer but the motion is smooth and reminiscent. If you have little green, these are better than a low-grade elliptical.

This one will not take my weight - but it's probably the best value dollar for dollar in a cardio machine.

Lifecore's LC-990 has a stronger build than most of their offerings. 350lb limit and compact size are plusses. 17 inch stride is a negative.

Interesting geometry - like Horizon.

Huge and arcane - but brilliant geometry and exciting styling.

Upgraded electronics and footpad adjustment.

ditto

Spirit Fitness' EL line has a similar beefy build to Sole but at a lower price.
