Nice guitar, I'd like to try an ovation at some point haven't had the chance yet but they seem really unique and have some great looking designs too.
I do usually get strings when poking around local music shops but for awhile I was ordering direct from d'addario chasing those points, but I like trying out a variety so I'll pick up a couple at a time one I've used I know I'll get some time out of and whatever I haven't tried yet or catches my eye. If I didn't have the option of nearby shops I'd probably just stock up a couple times a year or try to order direct from manufacturer if they offer it.
