It is quite interesting to see this from both sides - I can appreciate the sentiments of those frustrated members who have paid good money and are still waiting for news about the figures that they have paid for, when it seems everybody else received theirs from other sources ages ago. From that perspective, it is easy to see how frustration can turn to anger. I'm not sure how helpful it is to guess why the delay have occurred - I would be surprised that with the delays that OSB have experienced, they would be "holding out for a better deal in Hong Kong" whilst their customers were getting ever angrier.
I also wonder if OSB could have avoided some of this negative feeling by posting some updates on their site to help explain what has been happening in terms of delays and announcing when items have arrived (although I do appreciate that it is hard to do that if you are ill as is the case for Wai Man). I see that lately, Mazz has been doing this on their Facebook page and people have appreciated the reply even if there has been no new information.
Personally, when I have emailed, I have received a reply. I am still yet to receive my first order from them but I can wait and I'm pretty sure I won't die if everybody else gets Starboost before me. I have also continued to pre-order some of the stuff I wanted in spite of becoming aware of delays on this thread. Why? Because their prices tend to be the best - they are consistently cheaper than every other seller in the UK (grey importer I know, but the figures are the same). Sure, every now and then Sideshow may do some freak discount/sale thing where they turn out cheaper but that is not common and nobody is able to predict which figures they will do that for. At the point of pre-order, you know that the OSB final price will tend to be at the lower end of the range and if you are thinking of multiple purchases, those savings all add up! Also, posts from the likes of inked and jimbits have given me re- assurance that OSB are not a cowboy outfit - just a small company going through a rough patch. That being the case, support rather than hostility is what they could do with, as the last thing collectors in the UK need is the loss of another source for our Hot Toys addiction (apparently, there are other brands too!) I don't tend to use one supplier exclusively, so for anything that I think I want sooner, I have recently found a great seller who is more local to me.
