Looks like it may have been out for a while based on the item description. Lookes pretty cool though. I'd be interested in getting more information, and courious if they are still on the market, or coming soon.
Look at the lower center of this shot taken @ Rawafx's sectional track super speedway. The AFX electronic scoring worked fine during my visit. I'm not sure if it is two, 2-lane units or the 4-lane model. Bob has all kinds of 1/64 goodies in his SPEED SHOP not to mention the largest 1/64 car collection I have ever seen in my life. He has a TrackMate system for his other super smooth custom track.
Hope you don't mind me sharing & showing these shots Bob.
Don't know how they work, but I'm going to check into getting one. 200 bucks is kind of expensive for something you don't quite know about. Looking for a cheaper set.
Rereleases or not, they appear identical to my 8639E (single version Aussie release) with the exception that the sticker on the front control panel is different.
BTW, looks to me like they messed up the box photo. Mine came with stickers to indicate lane 1 & 2, or 3 & 4. They put the 1 & 2 stickers on both units.
These work excellent on a Tomy 4 lane track. I have used them quite often, finally broke down and went with the computerized trackmate version. I do have a few of them in my closet still, that I was planning on listing on ebay...Chris
