You can do it yourself, you just need to know what type of system you want, and how to install it properly. Then you need to go to your local gutter supply store/gutter installer, talk to them and see what they can get you or if you pay cash price on the side (not a check, but green backs). The plastic crap you get at the big box stores are junk and not worth the time, they dry rot and fall apart and you will be redoing them in a couple years. Another thing to keep in mind is that not everyone knows how to install gutters and cover systems correctly, there's a lot more than just sticking it on the house. The people that just sell them, more than likely don't know how to install them. Right now is the busy time of the year for gutter people. If you have questions just ask, I use to install gutters and cover systems and know about almost all of them out.
