I would take the offer, that the brings the price down on it. You could hold out for more, but you may well not ever get it and then get even less. It's 3 words and very long, and got the (S) so I would get the $75 while the getting is good.
I can tell you what happens to me, I got names I thought was great. Then found others, didn't think they was as great as I did. I kept them and work with my better names, when it come time to renew them some I did renew and some I left drop. Then next time it was time to renew them again, I had even more names this time.
But this time I thought, I'm letting most of them drop what was I thinking. And take the funds, I would of spent on renewing them. And got clearly better names, I learn much more about domaining. And could see my choices before, was not as good as I had thought. What does this have to do with your name, well clearly you can sell it for $75, and hopefully make some money on it.
The the hurts it and so does the (s), and being so long also hurts it. And you can do much better, for that $75 you will get and not have to pay to renew it to boot. That is my advice on it, of course as I said you can hold on to it for more. And may be get it, but may be you will not get anymore offers that are that good.
