Well the title pretty much speaks for itself. I know that a good laser level is a very useful accessory to get, but Lowe's & HomeDepot carry them for $15 and they're kind of bulky. Does anyone know of a good place to get smaller and hopefully cheaper ones? My friend made one out of a $1 pointer laser and a small lens, but it only lasted about 2 weeks before coming apart.
And while we're talking about handy accessories, are there any others that you find convenient? Like good apps or other tools? I know there are some Squad Builder apps, but I don't have a smartphone.
