Exactly Manweiser. It turned into a "i know more than you do about max workout heart rates, etc." Where in Ct are you? I grew up in Newtown/Danbury in the 1960s/70s.

But back to the OP question(s), if he is not really sure which to get, look for something used on Ebay or similar to test them out before investing $200 - $400. I found a stationary Magura trainer at the Salvation Army. I took it home and tried it but liked my rollers more because they were much more challenging to master. Once comfortable on them, they are fun! I think that for big aerobic work outs, go to the gym for spinning classes. Whereas I do find them useful, the fit of the stationary spinning bikes is never as good as my own road bike.
