Abus with a protec core? Your source is Securitsnobs then,right?

(I only know them doing that, and they are a good source.)
Let me check the prices and get back to you.
So EDIT:
Okay the shrouded Abus is superior to the Abloy IMO.
Otherwise they are on par, maybe I would go for the Abloy Pl340 because it's cheaper.
With Abloy you might want to consider the weatherproofing extra, depending on where you live.
Generally though I think Abloy makes better padlocks. Have seen slight rust on supposedly rust-free Abus products, though they exchanged it to a flawless one without any issue.
There are pros and cons of both key retaining and non-retaining, see other threads, try the search function to find them.
Maybe that is something you should consider on it's own as well. If you decided on key retaining/non.... that should make the decision easier, because the Pl340 and the non shrouded Abus 83 55 are on the same level IMO.
