The Reliable UberLight has been getting a lot of audiophile buzz lately. No suction cup but it's got a clamp or a round base as options.
I got a round base one in black and like it a lot. My ONE complaint is that its "off" switch is to hold DOWN the power button for 3 freaking sections. Look, I'm already missing the first couple musical grooves because I'm trying to avoid clipping a multi-$K stylus with the ring clamp, then I gotta dive back into seating, un-Mute, and adjust volume. I don't need to miss a couple more grooves because of a damn 3-second power button!
