keymaster -- clearly this group buy is not a good fit for you, and that's OK.
I think you were right when saying that this is for more "advanced" keyboard users. I might use the word, more "invested" in their keyboards, which of course includes the fact that they also spend more money, or have had several years to build up a collection, etc.
My point is that the rallying cry for GH members to participate is not about guilting people into it. If the GB isn't a good fit for you, then you shouldn't participate. It's as simple as that. IMHO it's more about reminding those of us that DO participate in a lot of these things
WHY this GB is important and that if you
have the means you should. ~$50 for modifiers may be a stretch for some, but ~$10 for the Escape pack is more in reach.
However, wether you choose to participate or not should be because
you want to, not because you were chided into it.
