Warranty: The Bowflex Treadclimber 3000 offers a more extensive warranty than the TC1000 model and covers the motor for 3 years, part for 2 years, electronics for 2 years and hydraulics for 1 year.
100% Satisfaction Guarantee - Use your Treadclimber for 30 minutes a day, 3 days a week for 6 weeks. If you're not completely satisfied with how you look and feel, then you can return your unit and get a full refund (minus shipping costs - just make sure to read the full conditions.)
Transport Wheels - Transport wheels on the bottom of the unit make it easier to move the TC3000 around. This is handy if you are short on space or for cleaning under the unit. Also the unit itself - with a footprint of 28.5" x 46" is actually more compact than most treadmills.
Improved Console - The TC3000 offers a much better console than the TC1000 with 2 water bottle holders, 3 more electronic function displays (Calories per Minute, Total Calories and Total Steps), 5 LCD readout windows (vs. 3) and a safety key.
Decent User Reviews - User reviews of the TC3000 seem to be fairly positive. The Bowflex TC3000 earns 3.5 out of 5 stars at epinions. Users really like the fast results and the low impact feel.
However several reviews have stated that it takes some time to get used to the feeling of walking on a Treadclimber. Others don't like the fact that you have to manually adjust the resistance.
Overall Conclusion:
Perhaps the main strength of the Bowflex Treadclimber TC3000 is it's ability to get you excited about working out (and thus use the machine more often). It offers faster calorie burning than a treadmill with a lower impact and a more compact design.
On the other hand, you do have to manually adjust the resistance of the TC3000 which can be a pain for some users. Also note that it only goes up to 4 MPH (this machine was not meant for running).
Compared to the cheaper TC1000 unit ($1799), the Bowflex TC3000 offers a longer warranty, higher walking speed, more electronic workout functions, more advanced console with 2 water bottle holders and an overall sturdier feel.
If you're looking for even more electronic workout functions, wireless heart rate monitor, more advanced console and an even longer warranty, you may want to step up to the TC5000 ($2499).
