OT: Scart Switch Question!

Sorry if if this is a bit off topic, but I am looking to by one of those 
Scart Switch boxes, which enable you to have multiple scarts using a
single 
scart to the tv.

I have narrowed my choices down to one of either of the following:

**my apologies if the links get wrapped**

Monster 3... from Play.com

Vivanco from Tesco Direct

So I was just wondering what people think of either of the above,
especially 
if you have bought one or other?

Many Thanks in advance & Best Wishes.
