Brands of string like Ernie Ball and Daddario are very good. But beware of counterfeit strings: buy from a reputable source.
I used to use Elixir (coated, expensive) strings for a long time, but received several sets that were, shall we say, of dubious quality, so I have gone back to uncoated Daddarios.
If you just want to try out different types of strings, I suggest Adagio strings which are available off
eBay. They are Chinese in origin, but of decent quality, and work out about half the price of, say, uncoated Ernie Ball or Daddario. I don't use them now, only because they don't make the really thick gauge strings that my new guitar needs.
Presevere with your playing. A few minutes each day is better than, say, one hour once a week.
