i was thinking of buying a pair of alesis m1 actives, but these samson's looked very decent too and for 150 euro it's a steal ...

what to do ?

You may also want to look at the KRKs. I think they are around $300 U.S. for 2. Some people really like them.

yeah... who cares how they look or how old they are... have you even turned the things on and bothered to listen to 'em? A/B those suckers and just go with which one sounds best to you!
