So i can kiss my Tivo goodbye.

I have trawled many sites and forums, and unfortunately nothing seems to stack up against the functionality of Tivo.
However , needs must and all that, so the choices as i see it are:
Ultraplus 9200
S7090,
Vu+ Duo ,which I have been told are due in NZ in approx 4 weeks time.
The S7090 I wont consider.
Ive had no experience with either of the other 2, other than what i read.
The Vu+ has a huge following if the forums in UK are anything to go by.
My main concerns are
series link or season pass as tivo call it.
not recording duplicate programs, as we currently have the same programs at different times on the same night, on some channels.
not recording series that have aired previously
Being able to add time to beginning and end of selected recording.
Is there anyone here that has used both and can advise on what they think of them.
cheers
Ant
