Hirogen, here's where you can get the adapters for Dragon heads to BBi/Hot Toys bodies--
http://www.goodstufftogo.net/html/bo...p?ItemID=18257
Each one costs $2.50 and Good Stuff To Go will charge you $3 for First Class postage (their minimum charge for shipping is $3), so it'll cost you $5.50 total for just one adapter. If that sounds a bit high for a small piece of plastic, then consider that the only other place I know that sells them is Cotswold and they charge $5 per adapter
plus shipping (Cotswold does offer a discount if you buy a minimum of ten adapters, but it's only 10% off the price, so the adapters would still cost $4.50 per piece). If you do decide to order from Good Stuff To Go, ignore what the shopping cart says for shipping when you check out (it said $7 when I ordered mine)-- they'll adjust the shipping when the order is actually charged and they'll include a receipt in the package showing the correct amount.
Hope this helps!
David
