I think that is the set that i was looking at!
4 Skylines, each on a different frequency.
ToyEast.com has the set for $38 USD (shipping not included), but they are coming from Hong Kong, so they will have to be shipped overseas and go through customs, etc. I was looking at ToyEast because I want a genuine Tomy Bit to compare my "clones" to. I was looking at the Speed Racer Mach 5 as my first real Bit. I'd probably use another body on it though, to preserve the cool Mach 5! The Mach 5 Bit costs almost as much as the 4 Lxx's!
But "regular" Bits are going for about $24. When is that next paycheck?
