I had a CAT 236B machine on the site at the time. I really worked it hard, but since them I have upgraded to the CTL, bought a JD 35D mini AND am in the process of buying a used Hitachi ex160 excavator from him. I think the key ot these sales guys is to let them knw you may be buying more than one piece of equipment from them so they don't try to make all of their money on one sale.
As far as lifting, all I can say is that it picked up everything I threw at it, but I couldn't pick up a full bundle of Advantech subfloor. I could lift it just enough to move it, but not off of the ground. I don't know how much weight that was, but I KNOW it wasn't light!
Once again, I don't think you will be dissapointed. It is a solid machine, as are most skid steers, but with the way the weight is distributed (60% rear / 40% front) versus traditional skid steers (70% rear / 30% front) if you are working on any slope, you will feel less "tippy" in my opinion. In fact, when I bought my JD, I wanted to by the CAT SOOOOOOO bad, simply because it was a CAT. But the way they both handled on a hill changed my mind to the JD (I am developing a subdivision which is almost ALL on a slope).
If you want, remind me with a call on Monday, and I will get my guy to give me a price on a 320 spec'd the way you want it. that said, with steel prices rising, it may not be far off since I bought mine a year ago. I will PM you my number.
One more thing...I spent the bucks and put on the McLaren Semi-Pneumatic tires...well worth the investment around construction sites!
