From what I have read here, VXP (eBay) is just a gimmick type of shop. Don't even bother with them. They are also way more expensive. All of your prop needs can be met either by OSE, Kintec, or the forum members here on the forum.

The difference is pretty simple. A de-tongued prop (classified as an M series) is pretty much the same as a regular tongued (X series) prop. The purpose of the tongue is to help "get a grip" on the water. An X will launch harder than an M because of this. The tongue creates drag at speed though. An M doe snot have that drag at speed which reduces the load on the motor, which also helps to drop the current ever so slightly. Because there is less drag, you are able to get a few extra miles out of your setup. The downside is that it is more prone to slippage/cavitation.

I hope someone else can come and clear it up a little more, but that's the gist of it.
