Just picked up some Tacx Antares for 40 notes, I'll take noisy bearings and possibly dodgy lock at that price!
I think for £40 I'd be happy. Some Antares are noisy some are not. There is a fix for the noisy bearings. The reason they are noisy is because the bearings vibrate on the shaft. The solution is to get some Loctite Studlock / Bearinglock. (Ask your local car mechanic or LBS if you can borrow it.) Then dismantle rollers, place a 24mm socket on the floor, place bearing of each roller over the top of the socket and use a rubber mallet tap the shaft, The shaft moves and the bearings come out, apply the studlock to the outside of each bearing surface and re-assemble, hey presto noise free rollers. The studlock does not stop you taking it apart if the bearings should wear. But if my instructions don't make sense, see link..

I don't have a fix for the dodgy lock unfortunately.
