In the spirit of full disclosure, I am the developer / engineer that develops and sells the ps3toothfairy. I encourage you to read a couple of user reviews for yourself at www.ps3toothfairy.com/elite
As for shipping, if you order today with a credit card, it goes out no later than 2 days, most orders go out the next day. I have them in stock. They ship via priority (us) and express (intl). I've recently changed to express for the intl orders because it is only 2-3 dollars more but is delivered in 3-5 days rather than 6-14. For domestic shipping I charge only what I am charged plus a small (1$ or so) for packing, etc. For US orders it is currently $6.05 and most users (except miami for some reason) get them in 2 business days, miami in 3.
The main differences are
a) that the ps3toothfairy uses the genuine Sony electronics for the bluetooth (so if the official Sony remote works, the ps3toothfairy will work too).
b) The user programmable and built-in shutdown macros are inside the ps3toothfairy. So you only have to trigger them and then it takes over and shuts down by itself. If you are using a Harmony, there is a PwrOff command in the ps3toothfairy device that does everything for you.
c) There is a boat load of user documentation, FAQs, user manual, etc on the ps3toothfairy website.
And one thing that may/may not be different is that users will say that my customer service is top-notch.
