Listen, I hand registered a domain on expireddomains.net... FunkyBot.com, now the reason I did this is because 1. It makes sense, 2. ...bot.com, funky...com domains have sold before (namebio), and finally, 3. It's brandable.
So... If you can't do that please stop wasting your hard earned money.
Btw, even funkybot.com has a 5% of selling, if that! Also it's not that good, I mean HotBot.com would have been nice as it sold for $155k this week.
Try to generally aim for the mass market, unless you really know what you are doing.
