Regarding the 24chickens article, I thought it was pretty good, although I don't agree with the NEVER SIGN A CONTRACT. However I do believe you need to be educated as to the consequences of the contract.
First off we sign contracts in one form or another for just about anything. I mean download something or try and install a program and you sign a contract, you agree to their terms or you don't get to install the program. Buy a house, rent a house, get a cell phone, all involve contracts. You agree to their terms. Sure you can line through something on paper but.... is it really realistic, I've never been able to edit a contract for a program on my computer.
If you have investigated the school, and it has a good track record, you like the style, you like the school, you like the instructors (owners) etc. etc. I don't see the need in spending an extra 40 bucks a month just so on a whim I might drop out. Because if you are planning on staying and learning something of value your going to be there for several years, so in the big scheme of things a 9 month contract saving you $40.00 a month isn't that big of a deal, but it can save you almost $400.00. Now if they were wanting you to sign a 3 year contract to save you $40.00 a month, I'd balk about that.
And while the short 9 month contract might lead to longer contracts you can always refuse and go month to month then. If they come back with the short contract and it saves you money then you can sign up again.
