Yeah, be careful about regging names that almost sound right. The singular wouldn't even be worth much, though it is better than the plural you have. If you are new to the game in 2010, then as a general rule you should probably avoid regging names until you have a few months more of knowledge. The odds are so very low that you are going to come up with something like this that is worth something, it is best to avoid it altogether (tough to do, though).
I would try to buy very cheap names and have a little fun trying to sell them (while parking, also). You could even start a Names Wanted thread and ask people to send you some cheap names. You can pick up names of value for less than reg fee sometimes that someone just doesn't want anymore. I have bought and sold names this way many times.....often essentially giving away names I thought had value, just to clear some space and keep the deals flowing......same thing with buying......I bought a bunch of names the last two months.....some worked out, and some didn't.....I paid anywhere from $10 to $200 per name, with lots of deals in the $30-$40 range.
You could probably pick up a bunch of names for a few bucks each. You can sort through a few hundred names that people send you and then buy the ones that you like the best. You will get lucky a few times if you have a good eye.
Good luck.
