factory radio removal

can someone tell em the difficulty removing the factory radio on a 1992 buick lasabre. im not sure if i should save the cash and do it myself or just pony up the money and get it done. Ive installed to aftermarket head units before. in my 87 s10 it was really easy but in my brothers 97 blazer it was hell. if it is going to require ripping of most of the dash like on the blazer i may just spend the 60 bucks (with parts) and get it installed
