Now I've only just recently done a transaction with RussRep, and I'm in the waiting process as well for my gauntlet darts. I've sent a few PMs and e-mails his way to clarify a few things with him pertaining to payment, and although its taken a bit for him to respond, he has indeed responded.
As the others have aready stated, we all have lives outside of this community, and they will take precedence over all else... even when we don't want it to. So a little patience can go a long way. For those that feel uncomfortable with long waits, keeping in mind the 45 day limit for disputing on PayPal, then it's your perogative to ask for a refund.
In a nut shell... we're all here for the same thing, our love of Fett/props, and it's unfortunate that some have gone ruined the comfort level with on-line dealings. I'd like to suggest, that even in light of all this, that you give RussRep a bit more time as he's yet to make a bad name for himself.
