Most acrylics can be laser engraved just fine.
On the catalog, if I may I'd like to make a suggestion. First of all, don't make a catalog. I assume you want to do this because you want to afford your customers the same choice we have in styles and types of pens, and in variety of available materials. If you find people that appreciate this mass of information, they will drive you nuts picking out what they want. Then you have to gear up - bushings, kits and such - for that style, as well as keep the various materials on hand. Instead, I suggest that you pick three or four kits that YOU like, and stick with just those choices. Lets face it, unless you have really bad taste, the styles you like will also be the styles a lot of people will like. And when you make a pen you like to make, you just naturally do a better job! Same for the wood or acrylic you use. Stick with just a few things you do well. That doesn't mean you shouldn't try new things and offer them, but I would only keep a style in production if you enjoy it.
I also suggest, like Daniel, that buying pens is much more than an intellectual excersize. If it weren't, we'd all write with BIC's! Everybody has their own reason (or not) to buy a $30 to $50 pen. Most generally it is because the pen satisfies some need they have to own something special. So if they percieve your pen as special, they will buy it. Ordering option A and option B out of a catalog is not conducive to getting that "special" feeling. Actually, holding the pen, getting that tactile response, seems to work for most special pens like ours. The beauty of our pens and the way they feel is so important. When selling pens I start by asking the person which pen they like the best, and I will pick up that pen and hand it to them. As they are touching the pen and looking at it I tell them about it, what wood it is, where it comes from, what finish on the metal, etc. Some people form an instant connection with the pen, others never will. But it is the "experience" of a pen that people are attracted to.
Just my opinion.
