Definitely worth the cost, Lelo has the best customer service as well so if your toy stops working within a year after you purchased it (hang onto your receipt and serial number - I just stuck mine in the little compartment in the box the toy came in) you can exchange it for a new one. And I think if it breaks/malfunctions within 10 years you can still turn it into them and get 40 percent off a new toy. My original Ina finally bit the dust so I shipped it into them and a week later not only had they sent me a brand new replacement but it was an Ina 2! I can't say enough good things about the excellent quality of their products and customer service.
Compared to a lot of other costly sex toys Lelo is definitely a better deal when you consider you are pretty much buying a toy from them for a lifetime. I've worn out the motors on plenty of other toys that weren't cheap either but I don't know of any other company that will replace them for you to the extent that Lelo does.
