Topic: cheap multieffect

I was thinking about small, non-expensive multieffect and I have a question. What do You think about using multieffect on modeling amp like Fender Mustang?
I found the:
ZooM G1xon guitar effect procesor
Line 6 Pocket POD Guitar Amp Emulator
Vox StompLab IIG Guitar Multi-Effects with Expression Pedal
Which one do You recommend?
