If you're serious about getting into Bonsai, then join a club You will get hands on guidance and different opinions. If there are no clubs around, then read, read, and read. Then maybe you'll feel comfortable working on your own. Personally I never bought training pots, or paid full price for Bonsai pots. I make pots from old garden center pots and found pots in flee markets and small garden centers that sold pots on sale. Some were even given to me. I personally think that for the first 4-5 years, it's all about keeping certain species of trees alive. So it really should not matter what kind of pot it's in, until you want to show it or begin it's long distance training.
