I think it's nice and all that you are promoting your business and want to give people an idea of different alternatives, but don't mislead people into thinking painting is something it's not. Annodzing is super expensive and takes a big initial investment (tank and supplies, etc). Yes, I am just repeating what you said. However to say that painting is anywhere as good or "cool" as annodizing, is just a load of bull if you ask me. I am involved in the sport of paintball and you'd be amazed how customized these things can get. At least enough to rival, if not exceed PC Case modders. Anyways, I have had annodizing, powdercoating, and painting. By far annodizing gives the most interesting results. When you paint you are adding a pretty thick layer on top of your surface. I am not sure exactly how much (i am sure you can tell me) but compare it to annodizing. I bet it's a good difference. I think a good middle ground is powdercoating. It's much easier to do compared to annodizing but also does not cost as much. It is more expensive than painting though of course. It makes a good middle ground since you have all the flexibility and creativity options as painting for a cheaper price.
So, IMO, it would be a) annodizing b) powdercoating c) painting in terms of affordability. Annodizing would offer maximum cooling properties then powder and then painting. Maybe the last two are tied. Just because you can't annodize (or don't want to offer it), don't preach about how bad it is and how great your paintjob is.
