I got a lovely PME tilting turntable for Christmas and I love it. Makes piping side designs easy , it is fully adjustable and has a really good non slip surface so the cake doesn't slpi even when on a considerable angle.
I use a lazy susan for my turntable, bought from Ikea for $7. It's not fancy, but it's large & works great for me. I just couldn't imagine shelling out $50 for a professional turntable; but maybe that's just me.
