Hey, you can ASK for any starting bid you want. Those prices are pretty close to what the Beetle cost from INDY R/C and less than what the Silent ST kit cost.
Only the Curare and the Arrow are unavailable as the other kits are still listed in Singapore hobbies most recent price list.
Silent ST - 818.40 SNG = ~ $535 USD
Beetle - 569.90 SNG = ~ $372 USD
Joker 60 - 412.10 SNG = ~ $250 USD
SHipping is about $35-$55 USD.
They are all great kits (complete hardware included), but not a great bidding strategy for Ebay. Plus it takes the fun out of getting into a bidding battle

I agree with ppljr - I'd rather have an Addiction 110 kit for that much money, but that's just me.
Now there's an MK Arrow .60 kit out there which is being bid up more conventionally (low start ... ridiculous finish; well, we'll see about the finish)
Happy Bidding!!!!
