Is semi dry is for scuba, full dry is more of a snorkeling set-up ??

Now for regulators I dont plan to go over 100 feet for a while so what am i looking for in a regulator? Does it have to be over $500.00 or is that more for like pros diving beneath the ice and stuff. I want "Good" beginner gear
not the cheapest crap for swimming in a stream, but not the most expensive that it will be a waste in a year when i upgrade, any makes and models will help.

buoyancy compensators again what kind of features do i want a BC vest to have? remember im a beginner but i do want a good one

Also foot cramps from fins how can I help prevent this? maybe a new fin or a good exercise? ill read the forums for these answers but if you can help it would be great
