How many people out there have top force and try to convert it to a tf evo?.Just wondering why they do that?.Are the tf evo that hard to come by.Also to buy an orignal top force is getting heaps harder ,even the re-release arn't that easy to get any more.I have managed to obtain a mint tf evo ,and good condition [58100] top force,was this a good investment for the future?,the evo also has orignal esc from 1991 , will this make a difference to future prices.
