I'd steer clear.
Consider the damage done if the shift ball inside fails and drops into the turret.
Leave the uber-budget builds to chumps on YouTube who have someone else paying the bills. There's plenty of people willing to buy ebay crap without recommendations, and unless you're interested in dropping a trans, there's really no need to cheap out on that type of upgrade.
As an aside, I've had both - but for my SC G35 Coupe, I bought a reputable shifter (can't recall which one) and it endured TONS of track time.
