Topo map of Mackinac Island for Etrex Venture

[Quasind]

I am looking to buy a small GPS for my camera bag.  I settled on the Etrex Venture HC.  I specifically want TOPO maps of Mackinac Island, Michigan.  I tried the search feature, no luck.  Does anyone know if Mackinac Island shows up well on the Michigan Topo maps listed on this site.  Or is it available elsewhere?
Thanks.
I found that MAPS4GPS map (http://www.gpsfiledepot.com/maps/view/154/), sounds perfect, but I am unclear if it will work with an  Etrex Venture.  Can anyone verify it will before I buy the Venture?  And does it include Mackinac Island for certain?
Could I verify the coverage by downloading to my PC?

Well this one should be your best bet:

I have a Venture HC.   Don't know if there is a real difference between yours and mine except for the color feature, but Mackinaw Island area (from the Michigan Topo here) will fit nicely on mine.
