Replacing the power liftgates on the back of the Lexus

What is your question?

Lexus Dealer retail price is $180 for each lift but there other lifts available on the internet for considerably less money. However, I have no way of knowing the difference in quality between the Lexus lift as compared to other aftermarket lifts. The lifts on the Lexus look pretty ordinary and I have replaced lifts on minivans over the years and they didn't look much different that the ones on the Lexus. Any comments?
