Before I get to my question, I do realize how many threads I post on here. I have a moment of embarrassment every time I post a new one because I picture all of the rest of you going "jeez, this guy again?" but I'm honestly just an inquisitive person who asks a lot of questions and I mean isn't that what this website is about? I know I sure like answering other peoples' questions on here. But I digress. I'm really interested in pens that have a built in piston filling mechanism and especially interested in vacuum fillers. Where is a good place to start? I'm considering purchasing the TWSBI Vac-700 as a gift to myself when I find a new job, but as to piston fillers, I have no idea where to start because they seem to be a lot more common than vac-fillers. Are there any piston fillers in the same price range as the vac 700 ($65.00 on Goulet Pens)? The only one at which I've looked so far has been a Pelikan but it was $200 and that is just too far out of my price range right now. Any insight is appreciated.
