I am a little over 5'7" and have never had a WSD bike, but that does not mean I would not choose a WSD bike if I found one that I liked and it fit. I have had a steel Bianchi -- Veloce frame -- that I built by hand-picking the parts to put on frame, thus not having to worry about it fitting from the shop. Of course the frame had to fit first. I have found, being 5'7", that a 52 cm - 53 cm toptube is a good "frame range", assuming standover works with my inseam (I have fairly long legs) and seat/head angles work with the toptube length. Knowing your "general fit range" will help you decide which frames to look at -- both WSD and unisex/men frames. I feel you find your frame size will be within a certain range, no matter if it is WSD or not, but the big question will be what components and how the bike fits overall. However, if you find a frame you like, than a good LBS will work with you on swapping out stems, handlebars, saddles, and the like to make the bike fit you. So, feel good about being tall ... it really helps in giving you more choices, as long as you are careful about picking your "frame range". With $1700 budget, there are a LOT of great bikes you can buy! Good luck!
