It's really not that difficult, just follow the rules set forth on the DMV website.
As for it being cheaper, it really depends. On average, Florida has some of the highest insurance rates for auto and is the highest when it comes to home insurance. Obviously location matters and many of the companies in this state rate heavily on credit. So if you have awesome credit it can be pretty cheap for auto but if you're in the mediocre range, divorced / single or not a property owner things can change pretty rapidly depending on the company you shop with. One thing is certain, prices will be all over the board depending on who you call.
As for everything else its still a great place to call home. No income tax and reasonable sales taxes are a plus and the property taxes aren't so bad so long as you homestead and aren't flipping homes every couple of years (paying more and more as you go).
Still a lot of land but SE is pretty filled up at this point. SW isn't so bad and middle to the north of the state is wide open.
