I can personally vouch for ASIN B013H2QN5S -- that's the wireless version. It has held up really well for a little over 3 years now, but some of the reviewers mentioned issues with it if you leave the charge cable plugged in 24/7.
For the corded version, ASIN B00XM1PKY0 looks to be legit, provided you can find it from a non-scammy reseller. I've also seen this sold under the brand name "Vibratex." It's still Hitachi, or at least it was back in 2010.
