Wait to see if Team Associated will do another re-release of the Worlds Car or the original gold pan.
I'm the same way as you, I got bit by the nostaligic bug and ended up picking up a World's Car.
The World's car was the pinnacle of production RC10s. Had all of the top parts (Stealth transmission, black tub, upgraded suspension, anodized shocks, misc graphic parts, etc..) I picked mine up a few years back for $180 as a rolling chassis.
They may pop on ebay from time but most are overpriced.
The pinnacle of RC10 is still Misami's "Stealth Car." You can actually buy the parts now to make a copy of it.
Here is a cool thread on RC10 talk. They have a great vintage forum btw.

Almost a 30 year old design yet looks so modern.
