We live near Orlando and we have a Sunpass. We use the one that can change car to car even though we only have 1 car at the time. I think we paid something like $25 for it. We keep $25 at a time on it and because we don't need it every day that lasts us about a month or so.
The differences in the sticker and the suction cup SunPasses that I know of:
I the sticker is $4.99 (it used to be at least).
The transferable one like I said is somewhere around $25 I think.
The more expensive one beeps when you go through telling you they took the toll, and it also gives a different beep if you are running low on funds, and then it has a different beep if your Sunpass has just been refilled with money.
The sticker does not beep of course. And you cannot take it off and on because it is a sticker.
If you drive down once a month you will have to decide if you care enough about being able to take it off and having it beep to pay for the more expensive one. We got the more expensive one because we like to know when it is getting ready to put another $25 on it (it does this automatically when the balance on the account runs low).
There isn't a discount for having either in tolls. Well in some areas, but not in the areas we use them. Back in IL where we lived if you had the I-pass it was something like half off. Not here
