okay, to answer a few questions, you can purchase a laser pointer mount i think from either york or bintel for 20 - 30 bucks.
Why your alkaline makes your laser brighter, because they output more Voltage than rechargeables.! it depends on how crafty you are but there is a thread in the projects and articles page that deals with keeping your laser pointer on without holding it, but a bit of a quick think about it should see you with a operating solution!
Yes they are good but remember at star parties make sure nobody is imaging, you might just get a bit of cursing otherwise! and to keep them away from planes and what not (common sense)
