What brand hpt or opk do you use?

Lauren • Married August 2014, first born July, 2016, #2 coming December, 2018.
Gearing up for month 8 of TTC and I have successfully depleted my stock pile of test supplies. (Self admitted pee-on-a-stick-aholic). Anyone have recommendations on affordable but reliable brands to buy? OPK or hpt; I'll need both. Thanks!
