DX rifle scopes

ok, so im an astronomer and want to atach my laser to my telescope, and after all this looking around i realised DX had some ok units that could actualy 'zero in' or align the dot/beam with your scope.
but, the green 20mw seem a bit dodgy and 'overpriced' (for DX).

so i though maybe if i buy a red one and then put a 5-30mw 532nm module inside. do you think either of the following are appropriate and wouldnt need too much force on removing the module.

I am an astronomer also and 5mW is amply for astronomy. This is all I use and anything more is an overkill and may attract unwanted attention. This is what I have.

I also have that mount listed. The laser is the most useful I have ever found. It has a red and white flashlight also and the red has 3 settings and great for astronomy.

Scopestuff also has a great laser with mount. All 5mW and enough for astronomy, you really dont need more than this and the beam, I find is still visable in light polluted areas.

The laser I have listed in the link is really bulit well, as a nice beam that accually goes further than my cheaper 50mW laser does, it's water resistant and dustproof as well as being soild.

yeh, i was going to buy that mount for $10, until, shipping was $30 (no shipping rorts there...)
