There are
other options, some cheaper. "Better" is subjective
Check out robotkingdom.com. I also recently came across toy-wave.com and had a very pleasurable first experience.
RK will give you postage costs on the spot before purchasing, but Toy Wave is like HLJ
in that you place an order, and have to wait for a day or two with the exact postage, then you pay directly through PayPal quoting the Invoice #. On a per item basis, Toy Wave seems US$1 more than RK, but RK's automated method of determining shipping charges makes their charges higher once you start adding a few items.
Of course, for any of the above, you'll save more by buying in bulk.
I just checked both sites and everything is sold out except for Skyfire at Toy Wave. HLJ has both in stock, so that might just make your decision there.
