You might want to take a quick look at ISellPens.com (standard disclaimer, no affiliation) and see what they have in the line of inexpensive pens. I've gone there, purchased some different sized pens for gifts for others. As Christmas is a long way off, I've also tested these pens, and by doing so found what nib/pen size works best for my hand. Another option is a visit to a brick and mortar store.
No cheap shots from the cheap seats please. I'm just doing market research. That's all. Just market research.
There is no requirement that you actually buy even if you are

ahem, drooling into your shoes and about to float the display counter as you hold the "Gee, could this be THE PERFECT PEN?!?!?" in your hot little hands. it happens. The sales people at fountain pen counters, by and large, understand this. If they don't, size up the character with the name tag on his/her shirt and drop the name of the hottest person, object of lust, or other matter that would get their little old hearts going pitter-patter and they will, the gods willing, understand.
Word of advice. Take cash when entering the fountain pen shop danger zone. Never take a credit card.
Well, almost never.
Oh fugeddabuddit, you're going to buy another pen. You are one of us, from that fateful moment when you hit "enter" on the sign-up page. We have the secret to the whole addiction thing. That is, simply, lie to yourself early, constantly or often about the difference between need and want. Want wins.
Buy 12 fountain pens. Buy 12 more. You get the idea.
I said we had teh secret, not the cure.
And welcome.
