IMHO, the Aero's are under priced, and if the Jr. Gent is a Dayacom then it is way under priced.
Considering the blanks you used, I wouldn't even think that a good price if you were simply selling them to her outright.
I've only used the Dayacom Jr.'s so I don't know about the others, but a Dayacom Jr. in Rhodium will run about $18-19 plus shipping. X that by three, and it comes to $44-47. Ad in the price of the blank and it goes up from there.
That's a minimum. If I feel a piece is worth it, I'll price it even higher. Note that I don't run it like a business. I'm just a hobbyist.
Of course if you using a Jr that costs $8, then that gives you a little more room, but I still feel that $45 would be a little on the low side if the components are quality, and that is a nice blank.
