The Classic is a good one. The ripple curves make for wonderful texture on glass dildos. My personal favorite is the Swell Wand.
I agree with Beck, I don't own the classic, but I do own the swell wand, and it's fabulous! They look to be a similar shape, I'd check both of them out if I were you, and feel free to let me know if you have any questions about the swell wand! Happy hunting!
P.S. I am in lust of the swirled blue! I plan to get it when it's in stock/with my next order!!!
