Generally I believe that most cel dealers price
VERY reasonably.  The one constant exception 
would have to be Curt, who I think charges way too
much.  But hey, if he can sell them at those
prices...  good for him.

But I stopped buying from him some time back 
because I noticed how ridiculous his pricing was.

Some items he does that 1000% mark-up.  There 
aren't many other dealers that I have seen do this
on a consistant basis.  And also, while you might
call them greedy, even if they use a 5000% markup,
it's their cels, they can do as they like.

The best way to combat being overcharged,don't 
buy.
