Which type of leg ext/curl machine?

[BuzzU]

Gonna get a leg ext/curl combo machine and was hoping someone has some advice of what type? Here is a link for two that I am looking at. I was also wondering how smooth the first one would be if anyone has used that type before? leg ext/curl 1 leg ext/curl 2 . Or if anyone has any better ideas or deals I'd like to hear them also. TIA.

get the 1st one, the 2nd one is total junk...

I agree, I had one on my bench and I HATE them. Plus at my height my feet are dragging on the floor, so I have to jack up the bench.

Crap crap crap.

I really prefer something on a cable where the force required to move them is somewhat linear, on the #2 example you'd have to load it up entirely with plates and it would only be difficult for a small portion of the movement, its worthless.

Good points Mudge. Thanks for the advice guys; I'll go with one like the first example.
