It might cost you more... but if you are serious about Olga, get Ella first. If you like it, like the design and the size and everything, and you know you like stainless steel... go Olga. BUT if you just want it to be a stiffer neck toy, go Gigi.
I want Olga just for the box, but look at the bigger picture here. You can get Njoy Pure Wand, Gigi and Ella, and other stuff for the price of Olga. Don't jump this decision. Make sure you know you like the shape and design first before spending that kind of moolah. Or pointahs.
