Short term certainly, long term there isn't. You only buy the chimney once. If you have intentions of living there for long time it will pay for itself and you'll have a chimney when it's all said and done instead of a venter on the scrap heat. Another benefit is that it will not decide to stop working in the middle of the winter usually when it's -5.
I know my Brothers 110 sips coal during warm weather so you're going to want to take advantage of the domestic hot water year round for two reasons. If you use a lot of hot water you'll save money and more importantly it will prolong the life of the boiler significantly.
One of the big issue I have with the venters is they exhaust usually near the ground, that's a problem in the winter and certainly not doable in the summer.
It's going to cost you perhaps $10 a month in electric to run the vent and that is going to add up over the years. Then you have the cost of the venter which is up in the air for how long it will last. 5 years? 10 years?
