TaylorMade 320, or Burner Bubble Irons

[ttime]

Ive been going back and forth with deciding what clubs to buy. I figured since Im a beginner I could buy some used clubs from someone. I got a great offer to get the old burner bubble irons for $50, 3-9 irons, pw, lw, sw. They have been used for 2 rounds of golf. Only thing that worried me is that they are an older model, but I was still gonna get them.

Now the problem is that I have found someone with a set of TaylorMade 320 irons 3-9, and pw for $150. They are pretty much new.

I dont know what I should get. The 320s are a newer model, but the burner bubbles are for a better price, and are oversized. What set do you guys think I should get?

Any opinions?
