I'm going to have to go with the others. Save your money longer or look for a better used one. If you go cheap you will only be cheating your self in the long run. I payed $270 for mine fluid/mag combo.

Now if you look around you will find killer used deals. Here is a link on craigslist to a trainer for $75

Now here is the same trainer on the performance site for $330

Thats a savings of $255 and the used one in the picture looks like new. Just my opinion, don't go cheap because if it doesn't feel good your not going to ride it. Its hard to get on it some days as it is. You will thank us if you take our advice. We have been in your shoes.
