$2000 sounds like a lot to spend on a PE device, especially one that is experimental. Do you have a link to a site that describes it?
Unless your urologist thinks it’s a slam dunk, I’d recommend you start out with hot baths and a hot rice sock. See where that gets you.
Because I am a cheap bastard, I would also recommend stretching with a Captn’s Wench. It’s very easy to make and works surprisingly well. I’ve built a 1” wide version that I’m loving. I haven’t tried the “Wenchette” with really heavy weights, but I can say with certainty that it’s very comfy in the 5-10# range.
