As an early Christmas present I got the Cycleops Jet Fluid Pro trainer. I got it from a mega-dealer on eBay for $299 which included free shipping. The best price online was $359.00. He shipped it out the same day he received my PayPal purchase. I also got the cycelops front tire stand to make the bike level. The trainer allowed me to use my existing quick-release skewer, but they include one in the box along with a DVD training tape. It took every bit of 5 minutes to set it up. Decent instructions included. This is my first trainer so I have nothing to compare it to, but I looked at Cycleops Fluid II and 1Up USA. The setup is very stable and without having to change out skewers I can get my bike in and out of the trainer in seconds.
My desire is to be outside, there will be days this winter that will force me to stay indoors. I don't want the weather to lure me back to the recliner and remote control so I got the trainer to keep me active during the winter months. I am guessing the days in the spring and summer with downpours will be a good reason to have one as well.
