What a weird poll - would you rather vote for the $50 TWSBI or the $900 MontBlanc? A more structured poll with products that are all at similar price points would be more helpful. If your budget for a FP is $75, a $900 MB will not be of much use to you even if available.
I agree that a poll where all the pens are within the same price point (or +/- say $20) would be better than one with $50 TWSBIs and $900 MB. There is no way I could purchase a MB even if I had the cash, as I do not see the reason for me to own such an expensive pen.
If I remember correctly, TWSBI have said in the past that they don't do group buy discounts. It would be great if that changed, though, or if they would do something custom for a large enough order.
