That depends on what you are asking.
Something like the question you have asked, you would probably normally ask on the Dangerous Things website.
There is a floating help button on the bottom right.
However, Especially since, I may have put you crook in the first place, and called my Ultron an Ultimate.I will try to answer it for you, and hopefully, I get it correct this time!
I originally got The Ultron Upgrade Kit - Ultron MAX Kit for $199
I think Ultron kit was a NExT??
An Ultron Max was NExT + original Spark??
( for that same price now, you get NExT + Spark 2 + xLED ) Which is what I meant to say in my previous answer to you 
Which I will quickly fix up, to avoid confusion.
TO CLARIFY
There is:-
Ultron - NExT + Spark 2
Red / White Bundle NExT + Spark 2 + xLED
Ultimate - NExT + Spark 2 + xM1
They all include
Bundle Extras
I hope that makes sense, and apologies if I caused you confusion
