Yes, the pH meter will be the biggest expense, but well worth it. It's also something that you will have for years so a good investment.
No reason you should expect failure on your first grow. If you follow the advice given here, keep your pH in check and feed them right you should get good results. We've had many new growers like yourself pull off some fine grows on their first attempt. No reason you can't too.
