What about the Radline/Unimax 1/24th scale off-road "Master Series" hobby-grade vehicles? Looks like they've been out since Oct. of '07, but haven't really taken off yet.
It's my opinion that the only way they're going to stay in the market is by getting aftermarket parts made for them, and the only way that's gonna happen is if they get mentioned in threads like this one and board admins give them a forum of their own like over on R7R (mentioned below). Just my 2 cents.

BTW - I don't work for them or anything; I just bought 3 on eBay and would like to seem them succeed so they'll have a future in my collection for years to come.
