OK! Don't blame or laugh of this 'newbie' thread!

I've been researching for some time and i already found 4 encoders with different functions and prices!

Now, i'm confused enough and this question runs my mind! Wich one to buy!?
There's Keywiz (cheap, functional but no led funtions and the service doesn't seems trustworthy)
There's I-pac (for those who live in !Europe! (overseas tax isn't cheap) and don't want instaled a trackbal in the CP, cheap, easy to mount...)
There's MK64 (This one may be a fatality 'kidding'

I already saw the features and i think it's one good solution for those light addicts! But if it has no overseas buy option, i can forget it beause i'm Portuguese!

And finally, there's Hangstrom electronics wich i've saw many people using it but i don't know it quite well to comment!

So experts, any sugestions??
