Elektron Musical Instruments

Hello, I was considering buying the MD but I have seen alot of posts 
complaning of problems lately. after some time owning the MD have you 
found it to be full of problem's or would you say that it is still a 
well built quality piece that I should not worry about spending the 
cash on. I would like to use it in a live set up, is it relieble 
enough for that or is it better kept in the studio. well thank's in 
advance for any help.
