The 7mil should be a good choice. I use mine for the whole season here, which saves me the hassle of re-weighting back and forth. The range of temp I use it in varies from the high 50's to the low 80's. It's hard to get too warm, even at the higher end. I usually lose the hood and switch to lightweight reef gloves at about 75 degrees.

Is there any kind of basic guide for how thick a wet suit you will need is?
Nope, to give you a datapoint from my diving, if the water's in the 80s, I wear a 3mm jumpsuit. 70s, a 7mm jumpsuit. Less than 70, I dive in a drysuit.

I know people who switch to a drysuit in the 70s even.

I will get my gear today and I am going for the 7mm. I don't like to be hot. I tend not to wear a coat even during January in St. Louis because it is too much of a hassle. But like you said when in the water it is easier to cool off than warm up. Just the opposite of what I am used to above the surface. Thanks for the advice.
 
I hope your dive came out ok. I did a bit of diving at Mermet when I was working in St. Louis, and it was cold! My instructor broght me a suit to use, and it was a 7mm farmer john. I hated it (too much suit!), but we went to 60' or so and anything less wouldn't be enough.
