Each one of the deputies has different features 
that might give you an edge. Some will give you 
the edge of timing -- a bid placed at the *right 
time* might win where it wouldn't normally. Others
will give you an edge financially -- your issue 
might be money, more then when the bid is placed. 
Some deputies have great prices for expensive 
stuff, but lousy prices for little stuff, or vise 
versa.

There's more than that too. . . Different 
deputies accept different types of payments -- 
maybe it's a holiday and you don't want to risk a 
large IPMO going missing in the mail, so you 
might pick a deputy that accepts Paypal. Or you 
can't possibly put anything more on your credit 
card and you need a deputy that will take an IPMO.

Etc, etc, etc.

If you want to write and let me know what some of 
your more common issues are, I can try to advise 
you on which one might be good for you. ^_^
