Hi There!

I'm trying to buy some concert tickets for a client.
He wants to see "Cream" in London between May 2 and May 6.

Here's the problem:  I cannot determine which of the online ticket
brokers are "reputable" and which are fly-by-night.  (I used EBAY
until October 2004.  But I was cheated on a big purchase, and stopped
using EBAY.)

A 5-star answer would be two reputable online ticket brokers offering
Cream tickets. Please note the important phrase is "reputable."  I
already have a listing of 18 ticket brokers.  My problem is this:  I
cannot determine which of the 18 are brokers with a past history of
satisfying customers.

Thanks!
