to answer your question:
how can the handle be too short? well there really is no too short or too long, its how easy you want to make it, the longer the easier...
the model 3 is $266 and that is for just the bender, no dies, no stand(which you can make yourself), nothing...the cost is pretty much shipping...
Bender $266
Die $225 (depending on which die(s) you get)
Shipping about $100 depending on what you get
Total now is $591
The hydraulic kit does not include the ram...it only includes an adapter to attatch the ram the the bender...again I am going to fab my own bracket...
