Amazon's list of 4K-capable streaming sticks got bigger - and more confusing - after its hardware event this week. The $39.99 4K Select will be released on October 15th, joining the 4K and the 4K Max. You're not alone if you find it tough to tell which is best just by going off names, and their prices might lead you astray; the 4K Select costs as much as the 4K Max, while the plain ol' 4K currently costs $24.99.
