anyone short torso with long legs?

I was just curious if anyone has had any good experiences with certain companies' road frames with the following situation: if you are short, have a short torso and long legs? I am 5'1 and have a 30 inseam, so I have had much difficulty getting a road bike that fits me correctly. I think there's a lot of companies starting to make WSD's, etc., but it seems like there's not a lot of higher-end options, unless you go custom (hey, I'd rather have a sweet bike than a huge house or designer clothes, :)

I think the top tube length comes into play? I think the shorter top tubes make it easier to fit on a bike with my situation. I wonder if there's other factors I haven't considered?

I ordered a Guru size 47cm with 650cc wheels, so I am hoping this will be a big improvement over my size 49cm Bianchi with 700 cc wheels with a much longer top tube than the Guru.

Thanks!
