Suggestions for a monitor for mySQL replication servers?

Hello all,
does anybody know of a script (pref. PHP or Perl) that does monitoring
of several mySQL replication servers in different physical locations?

I tried the mySQL enterprise Monitor, and it looks very fine. It is
also priced "very fine".... and is overkill for my use. :(
Maatkit also is too extensive for my intended use.

Basically I am looking for a simple page that refreshes every n
minutes and just shows the status of the replication on the servers
(replication threads, binlogs pos).

Anyone has a pointer?


Thanks already,

Richard
