Following on from an earlier message thread, can anyone recommend a
good biscuit jointer?

For the task in hand, I just need to be able to joint boards edge to
edge which means I think all I need is a jointer that will reliable cut
a slot that is
- parallel to the top surface (or square to the edge)
- a consistent distance from the top surface

Any other features that are likely to be of use?
Any features that just get in the way and waste money?
Best value for money?
