Guide :Optics : (1607225) Telescope

Lens size/ power

I got this telescope and love it. However, I cannot find any of the more powerful lenses from vivitar. Does anyone know where I can find some with a power greater than 100x that will fit this scope? I have tried ebay and the like with no luck. Thanks
