You can find pics of lower surgery results on many surgeons' websites. I know Dr. Miro has some and Dr. Bowers has some. Your best bet is to just sign up for transbucket, though, if you want to see pics.
And, FWIW, lower surgery results ARE promising. No, they won't guarantee you a 6" erect fully functional penis and balls that work like the real thing. BUT, a meta will get you a decent micorpenis that functions like the real thing, and many cis-men are born with those. Or, phallo will get you the size you want, though implants may be necessary for sexual function. Interestingly phallo discussions happen amongst cis-men with micropenises as well.
My lower surgery cost approx. $17,000 including airfare and living expenses. Would I like more size? Sure. But I am thrilled beyond belief that I have a dick that works.
