LG VX-7000

I was wondering where people are getting their vx6000 data cables to use with their 7000s. I see all of these cables on ebay for like under $10. Has anyone had any experience with these cheaper cables? I wanna get one and use the bitpim software with it. Are there any differences between these cheap cables and the expensive ones from, for example, Verizon? Someone lemme know. Thanks 😳
