In reply to mike123:
For occasional use it will be fine, there are better units out there but really i wouldn't bother unless you have spare cash (who has?) or intend using it regularly.
We use an Elite trainer although it is a bit further up their range, we have never had an issue with it, seems to work well, Mrs Edwards does a lot of miles on it.
Personally i prefer to use my rollers, its more fun, i have to concentrate, and it works the core muscles a bit,if i had to replace both the Turbo and the Rollers, i would replace the rollers first.
