Below is a list of sellers (in alpha username order) that I've done business with on ebay.  I tried to provide as much information while keeping it  short and simple.  I hope that you may find this useful and can use it as a reference in your future transactions.  Maybe we should have an online searchable database on sellers where we can all contribute?  It is small, but it is "work-in-process", and a start.  I hope to expand and may even re-organize as time goes on.

moonyu888 (Hong Kong)
CATEGORY: action figures
item(s): 1/6 action figure accessories
packaging: poor
tracking: NO, must send email followup on status
shipping: charges a bit high, ships via Airmail from HK
communication: poor
feedback: YES, must send email followup
notes: poor packaging of item, sent a replacement, did not need picture of damage, was extra cautious this

nonko583 (Osaka, Japan)
CATEGORY: action figures
item(s): 1/6 action figures (Cy Girls)
packaging: poor
tracking: YES, auto notifies buyer with tracking info
shipping: charges a bit high, ships via EMS
communication: good
feedback:YES
notes: i've had a few large purchases outside of ebay for cy girl dolls from him and each time
           one or more of the figureboxes were damaged even after assuring me it will not happen
           again.  i am no longer dealing with this individual since he packs the figureboxes very tight
           but forgets about protecting around the boxes.  plus he overcharges on the cy girl dolls with
           no discounts or refunds.  i guess he figures he can get away with it since it is outside of ebay.
