Triathlon bikes don't come in my size

I stopped by Sammamish Valley Cycle this evening to pick up some neoprene booties for my swim tomorrow morning. While I was at the shop, I figure I might as check out their tri bikes. They had the Cervelo P2C and P3C, QT, Scott and Light Speed bikes. Unfortunately, none of them fit me as the standover height was a little too high. The 48 cm Cervelo came closest to fitting me, but my crotch was still touching the bar. She recommended that I get a custom titanium Light Speed made for me when I am ready for a tri bike. Did I mention the price would be $6K? Presently I have a Trek road bike. When I looked on Trek's site, they did have a 47 cm women's specific tri bike that might fit me. Felt also had a tri bike in 48 cm with a low stand over that might fit me as well. I know that standover height is not how you judge fit, but it is a quick way to rule bikes out. Man, I wish I were bigger :(

Anyways, on another note, it looks like I will be doing nothing but swimming and strength training for the next 2 weeks. I read that with my injury I need to really baby my knees, so no running even cycling during this time - must focus on healing.
