I'm in Key Colony for the first week.
Where do I want to get my tanks filled and what tanks should I take down with me?
I can take a load of hp, or lp steels or newer aluminum.
And, any fill stations there to stay away from?
Thanks for the help guys.

Can't help you on Key Colony but if you go into Big Pine Strike Zone is good. They give you good fills on al and HPs. If you get a 10 fill card they fill for $4.50.

Gene,
I used A Deep Blue Dive Center, Hall's and Abyss last year, all with good results. I brought a mixture of tanks, steel 95's and 120's (all LP) and AL 80's. I used Deep Blue most often because they are located right on the parkway that takes you to Key Colony and you can get there easily by boat.

halls is a decent shop...not sure of how they are for fills...speed or price.

deep blue is handy...but again have no idea on speed or price.

Abyss just moved its shop, not sure how the new place is setup but they were a bit $$ on fills, and were slow. individual tanks were $5, not sure how much cheaper with a card. they use to only have about 4 whips...took forever to fill tanks if you had more than that.

we get all our fills through Tilden's Dive center (http://www.tildensscubacenter.com/) at mm50 or so. they have the capability to do 10 or so tanks at once, and i think 5 nitrox at once. they sell 10-fill cards for $35 for al80s, and $11 for nitrox al80s (maybe $12). so the prices are good. and you can pull your car/truck within 5ft of the fill station.
don't know how they are for overfills.

tildens is good. spent about a week going there and they were super helpful in trying to get you in and out as quickly as possible. you can't beat the 10-fill card price either.

Halls will take care of you, no problem.
Abyss & Discount Divers - stay away from.

Gene, I'm sure it may be to far, I stayed in islamorada during the 4th of July week and got my Nitrox fills at Florida Keys dive center. People were super nice. The dive shop at Bud & Mary's also does Air and Nitrox. I din't use them for Nitrox cause they were out of Oxygen the days that I needed fills. Good Luck and Be Safe.....

Btw, thanks again for hooking me up on those Armor gun bags.
