I like the NOCOs as well because the quick connectors are nice and easy to operate, even in the cold. I have a couple NOCOs around. I also have a Ctek 3300 that is in basically constant use on the XKR and it's been great, nice quick connects as well.
I also have the Eliminator unit Gurgie posted, but the larger 7A version. It can be set to 1.5A or 7A depending on what you're doing...I use it a fair bit too, more for charging that maintenance. It's fine too, just not quite as well built as the other two I mentioned.
The ring terminal quick connectors are a must, run the connector somewhere convenient so you don't have to access the battery every time.
