I've done what you're considering but you do need to consider 2 things. First, as has already been mentioned, decide how good of skier you are, and second, be honest with where you want the ski to take you. Are you at the beginning of an aggressive approach to advance into shortline, or is that not necessarily where you're headed with your skiing?
In my case, I was coming off a 1980's era ski, so most anything would be an improvement. I'm a better than average free skier (there's no local courses here ), but I don't envision working to achieve 38 off at this point in my life either. Based on that, I wanted a quality ski that has somewhat of a reputation of being easy and fun to ride. Did some research here and found a deal on a D3 RCX that was a couple years old.
