from what I've heard it cost's about 10k, and it gives you abnormal looking flaccid length. Researched about it, but I'm not too fond of going under the knife and spending a load of cash on it.
If you need anymore info go to http://phalloplasty.proboards.com/index.cgi , they have lots of information regarding penile surgery. From what I hear from that board, PMMA injection is the new thing now.
