I'm late to the party here but have to move 3 pins from our current house to a rental and then to our final place. The HF 20% coupon lasts to the end of the month and this would be $240 out the door with tax.

I just want to make sure I have the right 1000lb cart above - reading this thread I see that this one doesn't require modifications to work with vast majority of pins (I'm moving Sopranos, Star Wars Stern, Deadpool). The home we are buying has a nice wet bar in the loft area but I'm not sure I want to brave the 90 degree turn to get it up the stairs - its pretty damn narrow with the railing. This thread and others has me thinking I should give it a shot perhaps with one of the hand trucks I've seen on here
