Probably around $1000, counting all the optics, cases, and other Do-Dad's. Nothing compared to my other hobby,collecting antique pistols.>$200K in that one. But I look at that as an investment for old age. They are only going to appreciate in value. Lasers on the other hand will become cheaper.
Around 1989 bought a <5mW 670nm pointer (still works great, by the way) I paid around $40-50 dollars for it.
In 5-6 years Blu-Ray pointers will be sold at flea markets for $1 or $2.
Of course by then,they will have something 10 times as powerful and 10 X smaller.IE:Host the size of a AAA battery, all color lines including white, chose by sliding a small switch on the body=$25 or $30
I can't wait!!
