The new ones look like they are drilled and slotted.

They are Triple Drilled and Slotted Rotors. I believe they are Semi Floating Rotors. Just a Different Design.

They do look better but I would probably rather have full floating. Unless there is an advantage to semi-floating rotors? I don't even know what a semi floating rotor is.

Solid Rotor = A single piece of metal is bolted to the wheel.

Semi Floating Rotors = You have a center piece and a separate outer part that the brake pads touch. The two are connected by a bunch of round "buttons" that allow a small amount of movement between the two.

Full Floating Rotors = The braking surface is relatively loose so that it can move around to hopefully become in perfect alignment with the pads. Full floating rotors are less likely to pulse than solid or Semi Floating rotors. Full floating rotors make noise at low speeds as the parts move around, since they're kind of loose.

It appears Turner Motorsport still has them in stock for $179/pr fronts, not a bad price at this time.
I got a pair from them and a pair from Tischer, the first set is working really well so far.

Yup I ordered a full set of them yesterday from Turner fronts for 179 and rears for 150. Which is still a really good deal if you ask me.
