Aluminum is great if you regularly bounce off rocks and oyster bars like JT, but I still recommend going with glass. It's quieter and smoother riding generally. You just have to watch where you're going.
Here's a local option with an impressive pedigree:

He's located off Hwy 98 in Panacea behind the Coastal Restaurant.
Harry Spear was a legendary guide in the Keys and he's now building epoxy, one-piece skiffs in Panacea. His Low Tide is a two-man skiff that weighs less than 300 pounds and drafts 5 inches. Boat, motor and trailer packages start at less than $20K. Easy to trailer, easy to launch, cheap to run and easy to pole.
I'm going to add one to my fleet as soon as I buy that winning PowerBall ticket.
