I have a BOWFLEX ULTIMATE 2. I had a gym membership for 3 years and it was great. There is NO comparison to going to a REAL gym. Though... in addition to my Bowflex, I have purchased a professional quality Precor Elliptical Trainer and I am about to purchase a complete 'welded-plate' dumbell set with dumbell stands. It'll cost me about $3000.00 from Fitness-Depot but it will be well worth it to have some free weights again.
The Bowflex Ultimate 2 is definately the BEST home gym-type machine I have ever used though.
Also, I was banned from my gym for doing deadlifts nude.
