I play the waiting game too Acro, I quote the price once and it's the last time I contact them until they contact me... But their are domainers more motivated than we are, many are deperate for cash and will take what they can get.
I remember offering a domainer $300 a dot org, It was a catchy domain and very brandable, He was asking $2500 which was outrageous, I chose to forget about it and deleted his email, then he wrote me back saying he's open to offers, I told him $300 is all I'm willing to do.. This went on for 2 weeks until he dropped it to $500.. I refused again and told him $300 is all I'm willing to pay... Never heard from him again.
