A couple of months ago, there was a thread with an Eheim filter issue. The OP wrote to Eheim inregards to where they are manufactured. Eheim replied that the new series are still made in Germany but the "classics" are now made in China. So, the "classics" today are probably not built with the same quality they were 20+ years ago.
To the Op, there are plenty of very satisfied FX owners, so if that's what you want, go for it.
