Cryobanks

Maveric
I was wondering how people here feel about using a cryobank to have a child as a single mom. 
I've been considering it for years since relationships don't work. I'm 29 (30 in a few months) I have a son already who turns 10 this month. I've always wanted more children and, I'm tired of waiting for the "right" guy or, people telling me to. I have a good job, I've done it on my own for 10 years anyway. Why not??  
Thoughts?, questions?? I'm ok with that.
