Chances are if "most people can't get their hands on them", neither can you... regardless of whether you can afford them or not. If exclusivity is your primary criteria, you'll need to somehow find your way into some of the secret/closed groups on Facebook and hope you can land a spot on a list or be prepared to pay 2x-5x RRP for limited run mods. It's not atypical for hard to get $700 mods to sell for $2k or more on the secondary market - even then, you'll need to know the right people to get in the right groups.
