Are you traveling through areas often that need it? At least in my area I don't have a lot of toll roads...but almost everyone I've driven (Kansas, Florida, Illinois) most have pay-by-plate. Crossing the ohio river into Louisville -- they just mail me an invoice. Illinois makes it a little harder, you have to log on to a portal and create an account with your license plate number.
No hardware required. Last time I was in Florida, they did pay by plate --- if my memory servers. It costs just a little more, but you don't have do purchase anything. Tolls are higher though...it really depends on how often you'll be using it methinks.
It costs less if I do pay by plate in Illinois however it’s only good for IL. If I use I-Pass it’s good for most states but more important its good for the states I would travel.It's been a while since I got my ez-pass but I think its $25 but then they give you that much credit. It's available at most convenience stores. You need to setup an account and likely a way for them to auto charge when it gets below some limit. It might be $0 or something like $5. You stick it on the windshield near the mirror. Last year on our big trip to Arizona and back it was mostly accepted everywhere. Not Oklahoma though, got that bill in the mail which was like $65. Ouch.
I would use it 2-4 times a year.
