If this hasn't sold yet, I might be interested. But I'm hesitant likely for the same reason as others. At 2 years old, people will be worried that may be losing pressure or may have other tech issues like leaking depending on how hard it was used. These are fidgety machines. I might suggest that you take a cel phone video of it brewing a shot of espresso and post it here.
Not trying to rain on your parade but these machines can be bought for $450 brand new, with warranty. And as these fully auto machines are so expensive to fix (might as well buy new), people just don't want to take the chance that it will crap out tomorrow . Reviews show that this machine can shut down for no reason and when reset, work for another few pulls.. then need to be unplugged and reset.
You might get $100 if someone wants a fancy machine and will take the chance.
