Final Update
I just recieved my new Onguard/Magnum Brute lock. It is a redesigned model for 2007.
It looks like they've put some thought into this new model. The first thing I noticed is that it is not possible to turn the key until it is fully seated into the lock. Abus keyways are like this and I suspect that is part of the reason they work so well. The key also resembles an Abus key.
The second thing that is notable is that it is slightly larger than the older Brute locks. This is good for me as now I can fit it around the thin light poles we have here in Riga.
All in all it seems like a much inproved lock. Time will tell, but I think they might have a winner with this one.
