Do a search on the forum. There is a ton of info on
fasttech. I haven't ordered from them, but from what I've read, it could take up to 6-8 weeks to get your order. The majority of the stuff on there is clones/replicas, but don't let that discourage you. Most of the stuff also gets pretty good reviews making it a great value. FastTech also has their own forums that you can take a look at.
I have a Vamo V2 that I got from a local B&M for $45. For me, it was worth the extra $15 to not have to wait so long, otherwise I probably would have ended up ordering it from FastTech. Great device, and a great entry piece into VV/VW.
