Got a DWI....do I need a lawyer?

[Histrionic]

So I got a DWI the other night and blew a .14 after I failed the field sobriety test and was arrested. The legal limit in the state I'm in is .8. My question is if I need a lawyer or not. I have a friend that just got one ( he blew a .9 however ) and all he got was a probation officer and six AA classes. Obviously a .9 is different than my .14 though. I'm a little worried because I just graduated with a degree in politics and am worried about this biting me in the assss a few years down the road. Could a lawyer do anything to lessen the charges or possibly expunge/hide it in my record? I talked to one lawyer who wanted 5K. Another one wanted 2K. So of course it wont be cheap. Is it worth it to have them represent me in court or not? Thanks
