You can check with the folks at Gulfport Yachtclub or the tampabaycatsailors.com... there are some folks there that sail Taipan F16... and can give you an idea of possible F16 that are soon to be on the market.

From catsailor classifieds I pulled the following:

Taipan 4.9 F16 -- Sailed very few times, excellent shape & won the F16 Nationals. Comes with two mains (one for sloop rig, one for unirig), spinnaker and Hooter, Excellent rudder system compared to stock, Lightweight Kevlar built, Carbon PowerRighter Pole, wing mast. No trailer. $9900. Rick 305-451-3287, rick@catsailor.com, check it out at http://www.ahpc.com.au/m_taipan.htm (florida)(xxx)

An of course you can contact Vectorworks Marine, http://www.vectorworkssail.com./f16.html to inquire about a new or demo Blade.

I went thru the same process you're going thru, so if you'd like to PM me I can give how I arrived at selecting the F16 class.
