If looking for the best priced version - there are a few of the Hasbro versions floating around Taiwan on ebay at the moment for about $32 (with free shipping) if your source is priced above that... which looks to be the same as the JP version which is going for like $60 (but has a character card included).

I'm not sure how or why, but of the two Wave 6 Deluxe toys (Soundwave & Que/Wheeljack), both were released by Tomy in Japan, but only Soundwave was released by Hasbro in Taiwan (HK?) it seems. And it's definitely a Hasbro version, as they don't have the Character Card in them.
There is some speculation that they will still see a release by Hasbro in their new "Trilogy" packaging, but if and when that happens, is anyone's guess. (the toy would be the same, just the packaging will be slightly different - but getting them now saves worrying about it later if they shelve that idea and just focus on TFPrime instead)
