I've read some posts on this NG from people that had a problem with a IIIxe,
took it back and got another version that worked great/had a better
screen/etc. Are some of these differences because of different "versions"
of the IIIxe? And if so, how can I tell the difference between versions
when I'm buying? I'm about to plunk down $250 and I want to make sure I get
every penny's worth. Thanks in advance for the help!
