I've always had a nightmare time with alignment, and I recently got one of these laser alignment tools (recommended by many here). Sure it is expensive, but I don't want alignment to be the weakest link and such a massive inconvenience. With this I can be tack sharp in seconds, and check before each session to make sure. I haven't used it yet but may be using it in about a week so will report back..
