Yes, quite true! Sorry for the poorly written post. Had to run, rushed to finish and did not come out well.
Hopefully this will be better.
1) If someone didn't want to lay out the money for core charge plus the mod money all at once, could purchase one of these, send off, wait for it to come back and swap out. Sell his/hers and not be out much/any.
2) Thought maybe Stampede might want a spare(s) ready to go. Once setup to mod one, takes less time to do more.
3) Might be able to help out a member of the forum with a low price option and collect less dust in my garage.
