Thanks!
(Can someone more knowledgeable talk about that?)
At least if you contact the current owner, you may have a chance. He might hold you hostage since he knows he's got what you want, but at least you're giving yourself a chance.
Can't assume name owner will allow it to drop or that you are the only interested party.
A phone call may sometimes work. Frankly, the only strategy that works is one where you don't care if you get it. Don't ask me to explain. It's just true. Make the call. Explain your situation. Be polite. Since you don't care if you get it (you don't have to say that) you won't sound desparate and give cause to jacking up the price.
How will you value it? (I won't return here to tell you how but I'd suggest you scan prices at BuyDomains.com. They're pretty good a pegging value.)
If they do let it expire, it will not be released right away for a new owner. It depends on who the registrar is as to how long it will take to release. Network Solutions drags the process out for months!
