Tm is a good gun. They are excellent if you plan on leaving them stock. But once you want to upgrade them you will have to add more upgraded internals to handle the upgrade. Also they are not easy to take apart to work on. Thats where CA and ICS come in. They are easier to take down, especially ICS, and they all ready come pre-upgraded stock. They have metal bodies, metal internals, and a slightly upgraded spring. All these things you would have to add to a TM which can cost you some money. My advice for you is to make it out to a game and check out what airsoft is about. There you can see all sorts of different AEG Makes and models. You will find that many peoeple like showing off thier gear. If you ask they will probally let you hold thier gun and fire it off in a safe direction. Aslo the search feature on this site holds alot of wealth. I learned alot from it when I first started. But do not discount asking good questions though, especially before buying an AEG
You also asked about mis information. Well around here many people have alot of knowledge about airsoft in general and in many specific areas. My experience is that if your not sure about something but want to help, make sure you make it clear that your unsure of your information. Also there are times when someone makes a mistake or there have been people who just don't know what they are talking about and trust me, someone who knows the truth will make sure the truth is known.
Everyone knows everyone pretty much here, I believe.
