That's one sweet elliptical. I bought a Elcipse 1100hr for $399 the day after Thanksgiving and have used it 5 days a week since. Not the best one out there but it's worked well for me. The only bad thing about mine is that after buying it I found out that it is built for someone 5'5-6' and I'm 6'5" so the stride is kind of short. I usually burn like 550 calories in 45 minutes. For me it's easier to do 45 minutes of cardio a day then to obey a strict diet.
SublimeZM, my 550 cals is for 45 minutes plus 5 minute cool down. So in effect I'm on the machine for 50 minutes but only 40ish minutes are in my target HR zone.
