Having done group buys before, especially for large or heavy items, it might be helpful to look for LTL carriers near you who would give you a shipping discount on a large number of packages at once. Some part (probably somewhat substantial based on weight alone) of what is saved in a group buy might get eaten up in re-shipping once they hit the USA.
Regardless, after speaking with Cedric, I have high hopes that these are going to be a great option (93tzlegacy's SVX was the model for these, great pic here
