I use an astro systems barlowed laser available from SDM telescopes for $198

This works really well in a truss dob which enables an easy view of relfection of the barlow end in the secondary whilst fiddling with the primary adjustment screws. I haven't tried it in a tube reflector, but would imagine its a little trickier.
