SDcampbell makes a great point about the expanding foam. I just wrote in another post about contacting lamp shops and geting the expanding foam that is used by the lamp companies, very reusable. I would also advise going to Walmart or the like and and buying these large plastic chest they use for tool storage,garden storage, toy storage, whatever, and packing the units away in there, you can do single or multiple, they come in many sizes. I have also gone to the Goodwill, Salvation Army, and second hand stores and purchased old hard sided suitcases($5 or so on average) for shipping items in. I have done so with items to Europe many time with excellent rssults. Best thing you can do is pack it yourself as if you are sending it to yourself, which in this case you are. I have never had any problems when I have kept that in mind.
