Yes going to court is a total pain, we're in the middle of a small claims court action taking a non paying customer to court, and it's a farce beyond belief.
In small claims the judge only needs to be 51% sure in one parties favour or the other to make his/her decision, but you need to be able to prove your case, and if the other party want to they can make it very difficult by trying to obfuscate the truth and make claims that you then need to spend time, effort, and money refuting.
Unless it's cost you a substantial amount of money I wouldn't bother.
On the other hand if you're a member of your local chamber of commerce they have free legal help, so that might be worth a punt.
