NES Computrainer PRO (Racermate II) Question

[ChronoTriggaFoo]

Every NES version of the Computrainer PRO I've seen has come with a NES Top Loader. But I've run into a complete one (including Racermate cart) with a front-loading NES. Anyone ever seen one like that? They're asking $400 for it.

Thats the first release for the NES and is really not much rarer. They do show up from time to time and are worth a bit more than $400. Not a LOT more, but you could probably pull $500 if listed correctly on ebay.
