Yes, that's a handful of money. However, the Bunn unit is using expensive energy 24 hrs a day (I think). The cost should perhaps be equal after a year or two, and you're drinking much better coffee for years to come! A lot of my stuff, I couldn't care less, but my coffee maker needs to be the best, within some sort of reason.
I deserve it, don't you?
BTW, I also upgraded my coffee vendor to George Howell's Terroir Select Coffees. They normally have the Technivorm in stock, and have a great selection of roast coffees.
I won a Technivorm and it's pretty awesome: convenience of a drip brewer, but actually good coffee coming out of it. The gradations on the water reservoir are very convenient. It's my least effort-requiring brewer at home, and now, my most used.
