Eric,
I sometimes get a chuckle when shopping for something that is "new to me". The sales rep will point out a few features using meaningless catch words and trade phrases. Then ask me if I have any questions.
At that point in time, I inform him I don't know enough about the product yet to ASK any intelligent questions.
I am grateful, that a person, given the drive to do so, can usually educate himself thru the internet. Which makes sorting thru the BS spewed by an uneducated salesman easier nowadays.
Of course, if you want an expert opinion on brain surgery, just ask, I'm almost never ever wrong.

I thought I was wrong once but,,,,,,,,,,,,,,, you know how the rest goes.
Take care,
