When you say 'PFM' I'm assuming you mean PMF (Precision Metal Fab Racing). I purchased their 5/8" offset 530 for $60. It worked out perfectly for me as I needed that offset. I'm also assuming that you are looking at their 1/2" offset with a nose for $80.
I really don't know why they have that one with a nose - the only reason for having one is for extreemly high output motors or very large offsets - yours doesn't apply on either. I suppose if you were willing to part with the $80 you could buy it and just not use the nose.
Which gets back to the reason I'm posting. The output sprocket is subject to some healthy torque. I would be very cautious trusting welds on this part. I'm no expert, but I doubt that you will get the penetration necessary.
You may be better off in the long run to get the sprocket from PMF and just loose the nose piece.
