Reply to KRK rokit 8 G1 deal?

So my birthday is next monday, and I'm believeing of asking for money towards some studio/ live gear. I was originally planning on grabbing a UC-33e, but the only speakers I have as of now are desktop speakers. And I'm getting into production/ I dj a little.
The guy is asking 300, is this a good deal for Rokit 8 G1's or should I talk him down? Everything else on cl around here is rokit 5's with people asking close to retail...


Description:
"These are a pair of first generation KRK Rokit 8's with power cords and two 3' TRS cables. They are in great condition with some scratches and nicks, but no damage to the drivers. They were rarely used, in my smoke free home, and function 10 out of 10."

Should I hop on it, or pick up a UC-33e for my live set and wait for a better deal.
