If you want a WickedLasers, go for it. (I'm in no way promoting WL's products or anything companies' products for that matter).
WickedLasers mostly deal with pen style lasers which are compact but take in mind, a small laser will have to compromise on its duty cycle. Meaning that the smaller the laser, the shorter you can have it on and the longer you have the leave it off.
If you would like something that is compact and packs a punch BUT you are not going to conduct any laser experiments then the penstyle laser is for you. Take in mind that WickedLasers are not the only one you have to choose from, you have NovaLasers as well.
Laserglow, Optotronics, NovaLasers - they mostly deal with the high-end laser modules which are larger compared to pen style lasers. The size of the laser is indirectly proportionate to its duty cycle. So a larger sized laser will have a shorter duty cycle. There are some lasers where you can switch it on constantly without having to worry of the effects of duty cycle which means they have no duty cycle at all.
Keep in mind that pen style lasers have a limit on their power rating, and by the looks of it I'd say at the 125mW mark, thereabouts. The larger modules will have a higher maximum possible power rating.
When you are deciding on who to buy from, seeking IMPARTIAL advice is always difficult because there will always be some sort of biasness in their contribution brought about by their personal experiences (mostly).
Here is some impartial advice (I hope): The bottom line is, you have to decide what kind of lasers you want, then the power rating, then your budget and from who to buy from. Some companies offer fantastic customer service which is an important part in your decision.
You may want to try this. Perhaps email them first, and if they do not reply your messages within their stated time period then call them (emails may be filtered out by the spam filter). No calls? Forget about the company. In your email, you shouldn't ask for advice on what their lasers can do etc. you should ask general questions, but still in relation to lasers. The REALLY good companies will answer you questions regardless of whether it may seem that you'll want to buy their products or not.
Note: This may or may not work, so use at your own risk.
