If this type of service minimizes "their cut" to the bare minimum, and made it very transparent who it was coming from so i could price check, i would likely use this service because they're bound to have more TLDs (due to aggregation) than typical registrars.

Unfortunately, currently i feel like i'd just be paying a significant premium for something i already find too expensive. And if this isn't true, i see no information to indicate otherwise (at a quick glance, at least).
