Ya, It's good domain name, Before selling your domain, you can check the value of your domain name , It helps to fix the correct price for your domain.
I found a free appraisal service at http://www.zippozap.com/ .If you need, check your domain value here & fix the price for your domain.

better do a whois look up on the domain name at www.seowebanalyst.com zippo appraisal is very poor can't even read the alexa ranking not to talk of other metrics....that is a bad site for appraising a url.
safer to do a whois look up first then get caught up with funny appraisals, they all don't weigh the domain names the same.
from godaddy appraisal to validation site, but a whois look up will give you the perfect insight and what to belive when you do further digging with those appraisal site.
try www.seowebanalyst.com whois look up you will get more info there.
