Kona ***** Tonk
If you're looking for a road bike, check out the Kona ***** Tonk. It comes in at under $1k. I'm 6'3" and 225 and it works great for me (I have the 61cm frame). I'm guessing it will work well for you, but you are heavier than me by a bit. Also, since the bike comes in under $1k, you can spend a little more to get custom wheels made that can handle your weight and still come in well under $1.5k
