Here is my 2 cents.

What you can sell it for later shouldn't really 
be part of the decision process, unless you are a 
dealer.

If you own the cel for 2 years and love it, 
that's what it's for. If you paid $100 for it and 
can only sell it for $75, did you get $25 worth 
of enjoyment out of it? 

In my opinion, you should get the full $100 of 
enjoyment, and if you resell later, than it's 
profit back to you.
