Using numbers un domain name

Are domains that start with numbers bad for SEO?
Im gonna start a new website and i have found this domain available :
911"mykeyword".com ==> its memorable . but do you think its good for SEO?
And which one is better ? the last domain or another rich keywords domain (a little long)

Thanks

Its luck when you blend a number in a keyword and it gets good results.. Most of them aren't really good IMO..

shorter name is better in general, even if it has digits in it

the first name I ever bought in aftermarket was 1st- and then a couple keywords dot com and it does pretty well. I was a bit nervous about it @ the time, between the digit and the hyphen I thought i might be crap, but live and learn.

peace,

I think i will give the digits domain a try , i have seen alot of peoples that says it dosn't matter if there is digits in the domain.
Anyone else have tried a domain with numbers?
