My go-to toy is the Jimmyjane Little Steel Vanitas, which retails for $250. (The Little Chroma is the identical toy, but in aluminum, for less money. No bells and whistles, it just vibrates one speed, but it's the perfect pitch, no buzziness at all.) I also really love the Sasi ($149) and the Pure Wand. And everything Jollies made before they went out of business. Plus Lelo, I have five toys from them and they're all great.
My cheap plastic toys get used sometimes, but most of the time they just sit ignored in a Sugar Sak. I do keep several glass toys in the regular rotation, and not all of my glass cost and arm and a leg.
Yes, the high end stuff really is great. But being high in price doesn't automatically mean a toy will be awesome. Just read the reviews.
