Rayfoss 200s

Pardon the noob ignorance, but what are the main differences in the 200mW Rayfoss handhelds? Searching their page turns up QBT, QMT, QST, QGT, FLX, CO3, BO3, FGB, SWT. And the FMK, but that is IR filtered, so I can see why it is $80 more than the next most expensive.

But what do all these acronyms mean? I read the BO3 review, which helped for that model. I guess it depends on them being waterproof, having keyswitches, etc.

I will be getting one of these as my next green but not sure which to get. I guess the BO3 would be a contender.

Well, you just answered yourself. The names (QBT, QMT etc) are the differences between the lasers, like keyswitch, etc.. some are more expensive because of the different manufacturers. You should contact Faona (@ rayfoss.com@hotmail.com) and ask her. You should ask yourself:

What power I do need (for pointing stars you could use the 30mW one, etc)
Am I a good user (point it on your eye and voilá )?
Whats my budget?
What are my preferences according to my budget (do not expect a 200mW with key switch and waterproof for $30).
Why THIS manufacturer (Rayfoss is a very reputable seller, but if you are willing to spend $200 and want a 5mW pen, stick to laserglow, dragon lasers, etc)?
