Have leased many vehicles. The finance company can manipulate the payment (bi-weekly, monthly, etc) to be anything you want, provided you put down a large enough deposit or trade-in. So when you're shopping around, it's important to look at the total cost of the vehicle - downpayment + trade-in value + sum of all payments - to get a good sense of what you're actually paying, instead of looking at an artificially low bi-weekly payment.
Other gotchas are lease-return fees. You'll typically have to pay wear-and-tear costs on the vehicle, curb rash on the wheel, scratches or dings larger than the size of a credit card. Even if you've kept it ding-free, at the very least they'll still charge you the cost of a new set of tires (unless you've pre-purchased some kind of tire protection package). You may also have to pay over-mileage costs if you've exceeded the annual mileage.
Also, you cannot suspend insurance on a leased vehicle. Not that you would on a truck, but on something like a summer-only car, it has to be insured full-time.
If you drive to the US, technically you'll need a letter of permission from the leasing company to take the car across the border, but in reality, the customs officials almost always never ask to see the registration.
There are additional costs if you want to buy the vehicle out at lease-end. You're basically buying it off the dealer, so they'll charge you safety certificate, drive-clean test (if required), registration fees, plus all the taxes due on the residual amount.
