i don't think any mass produced product could ever look as good as something that was labored over for months by someone who really loves it.
that's why i don't get why folks mind when a mediocre, pre-packaged product comes out. it doesn't devalue what we do, it doesn't really change anything.
i've seen a lot of folks use the rubies vader as a gateway to greater things. you start out that way and move up from there.
those that are happy with the rubies suit as-is wouldn't want to spend thousands and years on a super suit. those that want the super suit would never buy a rubies. so it's just catering to 2 different niches, and may serve as a "gateway drug" to suck some in to our madness! 
i think the museum replicas stuff will be similar. it will be nicer than halloween costume, not as nice as TDH, and may inspire some people to bigger and better things.
