CycleOps Fluid trainer. Love it - good road simulation and it is very quiet. Also, excellent customer service.

I don't have any cyclo-core dvd's. A couple of CTS (Carmichael's) videos, which are pretty good, and a stable of the evil Coach Troy, which I love to hate and a couple of Bike-O-Visions with pretty CA scenery - I usually listen to my MP3 when using those.

I have never noticed any problem with my bike frame taking any abuse on the trainer, but I do have a rear wheel set-up that allows me to just change wheel instead of having to put on a beat-up slick every time I want to use it. I bought a used wheel that has the same rear cassette as my road bike, put a crappy old slick tire on it, and I just put that wheel on when the bike is on the trainer, sparing my lovely Conti Grand Prixs from the trainer and saving me the effort of swapping out tires every time.
