deanz406 has a nice gallery...have a look! Great collection of bipes, very nicely built and I like the colors. That red and silver Aeromaster is my favorite.
Whiptail, there aren't many bipes out there these days. Yet I went ahead with a biplane event in September and about a hundred people showed up, 18 registered pilots and 38 biplanes! They do have a special appeal.
If it must be an ARF, then Maxwell has some. But I really suggest you try building! The Phaeton II suggestion really seems the best for a first bipe with a 46 size engine. Just go for it.
Another route is swap meets. I picked up my Big John for $150 with engine. Then I fixed it up and repainted. Lots of fun...before and after...
