Not anymore:

Prime shipping, 3,955 pounds.

Hurry though, only one left.

This one popped up when I looked at the safe; it's about twice as heavy packed. Looks like a good Prime deal: http://www.amazon.com/gp/product/B001R23TE4/ref=ox_sc_sfl_title_1?ie=UTF8&psc=1&smid=ATVPDKIKX0DER

Actually thats no longer available and this SHOP FOX Belt Sander weighs over 2 tons so it would seem it has taken the honors.

That sounds pretty impressive, however I got you one better, 2,550# dry and 3,950# shipping weight to your door for free.

Now how you're going to deal with the requirement of 3PH 20kW is on you.

Worried 2,550# will dent your nice floor? The dual head model only weighs a paltry 19#.
