Are you looking for something that is a similar look to the pens you listed? I pretty much exclusively shop at Exotic Blanks and there is a lot out there to look at for options. I make a fair number of Diamond Knurl rollerballs and this year did some of the C Series also. I need/want to do more customization on the C Series and just haven't done it yet.
I would add this, don't underestimate your work.
If you feel it's $100 pen then charge that. I'd also add to go big. Ed Brown said something during one of his sessions at the MPG that has stuck with me. (paraphrasing) "If you want to sell a $150 pen then you should have a couple that you're selling for $200." It made me reevaluate how I did things and I've sold a couple of the "$200 pens" too.
Boy I hope I got that right but that's what I've had in my head. Ed can correct me if I'm wrong.
I would also say that a quality ink cartridge in the pen makes a world of difference too.
If you feel the work, components and look of the pen are worth a price then sell it for that price. You'll see a million formulas for how to price things, what someone says your or their market does, and all kinds of things. It comes down to what you think it's worth. If it's a less expensive pen or a super expensive pen it's much more about how you make it look. Unless your customer is shopping Exotic Blanks on their own they'll never know how much you paid for something. Just say it's a rollerball pen with an amboyna burl body and upgraded ink cartridge. They don't know if the components cost you $15 or $75.
I do have a day job so I'm not trying to make a living selling pens but I also don't want to sit on a ton of them either. Changing how I priced things did not hurt my sales in sheer unit volume of sales and certainly not in revenue.
