I've heard they're alright; most people don't bother with stuff like that anymore though, just go for a trading system. It's a one-time fee of like $100, easy stuff.

But what you do (and what I did) is make sure the trading system has a 60 day money back guarantee first; then make sure you can use a demo account. A demo account let's you play the trading game with "play money" so you can see if you can profit from the trading system without investing your real cash.

Use the demo account for 59 days and if you see you can make profit you keep the system and invest your real cash. If there's no profit to be made you get a refund and try another system; there's literally no risk when buying one.
