Elliptical for senior female with space constraints

[sararob52]

What is a good elliptical choice for a 70 year old female with space limitations?  Budget is open and durability is a key requirement.  The Sole 25 keeps coming up as a good choice but complaints about cheap plastic parts that break easily are a concern.  The Nordictrack SE9I looks appealing but comments about how bulky, heavy and difficult it is to fold down make me wonder if it defeats the purpose of that feature.  This would be used as a replacement for walking outside rather than rigorous training, so no bells or whistles are needed.  Machines such as the BowFlex are more steppers than ellipticals so are not contenders.
