Hi all,
 
I'm new to the group.  I have a 9 year old dc6 with the tkc100r and
tg100 units - it's in excellent shape.  I'm in the North SF Bay area.

*	how much I could expect to get for this unit  1) from a private
sale, and  2) from a dealer on a trade in.
*	I'm interested in a new or used dc5a or dc6a - what could I
expect to pay for these units after the haggling is all over.
*	how long it takes to sell and buy these units. 

Thanks for your help!
