ovulation tests

Ho
My husband and I are going to start trying next month if I'm not already pregnant now (waiting to see if AF shows up) and I was wondering about ovulation tests. I see some of you ladies using the clear blue ones with the blinking and solid smiley face   And others just use the strips. What are your opinions for each? I've tried the clear blue once before but I can see that getting really expensive really fast. Advice and opinions welcome!
