Disability insurance

I am in the underwriting process of obtaining disability insurance. Just wondering what everyone's thoughts were on the amount of disability insurance to get. People say to get full current income coverage which I understand why but the premium can be somewhere between $6000-$7000 which is quite pricey. I'm in my thirties so I do understand the importance of being covered but just wanted to see what everyone's thoughts were on the amount of coverage.
