My response was from my own perspective. I NEVER buy Anything with the hope that I can resell it for what I think I can. I've seen people sell K1000 (regular, not the SE) for over $100. I can barely give them away at $20. Frankly, and I've stated this in another thread, I' wouldn't buy anything 'as new' for pennies less than New, from a third party private seller. Especially electronics for reasons of warranty (which stays with the original owner). Some don't care but again, my own perspective.
That said, Everything I buy, I figure on keeping And Using. If I can resell items, great. If not, I have more clutter in my house. Some people here have received some nice camera equipment from my reselling. I do not however, Count on being able to do it. That, is what I meant by Bad Idea in my original Post.
I've never held a 7D and even had to check and make sure it wasn't a full frame camera. I remember all the hub-bub from when it was released and it looks like a nice camera. Not enough to make me a convert though. If I were going to dump Pentax for another brand, it would be Only for full frame. Since that isn't that important to me, I'll be here a little while longer (to the dismay of some, I'm sure
)..
