The LE model has a higher camera weight capacity than the SE model by approximately four pounds.
The LE model features a telescoping centerpost with adjustable height range, whereas the SE model apparently does not.
The LE model includes a larger-diameter handle with knurled grip texture.
The LE model's larger diameter post design allows for adding additional wires to support future accessory installation.

This discussion is from 2009 and reflects pricing and product specifications from that era.
The claim about wire-adding capability to the post is based on one user's assessment rather than confirmed product specifications.
No specific technical comparisons of the ISO-Elastic Arm advancement mentioned in the original question were provided by participants.
