Hi Eviscia,
Thank you for taking the time to leave such a detailed review and for sharing your experience using the steering stick on your route. We're glad to hear it has helped you feel safer while delivering mail.
As designers and engineers, we seriously applaud your attempt to make one yourself - that's awsome! Our company founder actually build his own driving school brake pedal to teach his kids to drive because what was available on-line was too expensive (and not well designed). Nearly nine years later, here we are! So we totally understand your comment on the price.
You are correct, we're the only seller. We're pretty sure because it's expensive to manufacture, the profit isn't much, and our design is really good. Our goal was to provide a complete RHD system that allowed to vehicle to be used for delivery and every day use. Plus, we didn't want to interfeer with the passenger side air bag deployment like a wheel/pulley system does.
We have tried to keep the steering stick as reasonably priced as possible and have only raised the price twice since introducing it 7+ years ago, even though manufacturing, materials, and shipping costs have increased over the years.
We appreciate the feedback about the handle grip as well and will definitely look into improving our designe based on your suggestion. One idea is to get some water pipe insulation with a little duct tape and modify it that way. Really inexpensive solution.
Thank you again for your review and choosing SAFEDRIVE as your RHD conversion. We wish you safe travels on your routes.
