I'd suggest something like Tantus's Ripple Large (bit more expensive but very nice ^^) (or small) or Doc Johnson's Groove (which is around the same price as the ones you picked)
I guess I'd pick the advanced.
I'd skip those altogether and go with something silicone. If you really like the shape, then the Tantus Ripple would be a fine choice. There's also the little pink plug in the silicone beginner kit, which is sort of similar.
