I have that model and had it for about 6 years and really like it. (Purchased for less than $500.) You do need a strong vac or dust collector for sure. Attaching the sanding belts are not difficult after the first time (for me). 95+% of my thickness sanding needs - fit within the 10 inch limits.
the Grizzly 10" is not cantilever - meaning you cannot sand half of a 18" wide board and then turn the board around and sand the other half. The 10" Grizzly has a plate on the outside edge with a hand lock to keep the drum parallel. I have thought about taking mine off and trying it on a wide board to see if I "could" do a wider board.
Look on the outside edge and you can see the somewhat triangular shaped plate with hand knob for locking it into position:

The two problems I had are this sander:
1. In a hurry, got it together and turned it on to see if it was working - no DC yet connected. TEMPTATION got to me to stick a 2 ft long 6 in wide board on it. Then it hit me: "YOU NEED A DUST COLLECTOR ON A DRUM SANDER STUPID!"
2. After that fiasco and hooking the dust collector to it, I ran the board through it again. Did fine. Wound the setting down a turn and a half (if I remember correctly) and the pressure on the conveyor caused it to stop. That isn't a defect. It apparently was built into it. It is not a bladed planer. The thickness sander does not like taking moderate bites. THIN LAYER BITES! Thin sanding bites/layers at a time. You know you are trying to take too much when the conveyor stops. Don't judge a thickness sander for taking off thicknesses like one would on a thickness planer. Lesson learned for me - from experience.
I haven't used it as much as I thought I would but I haven't had as much free time as I thought I would in semi-retirement.
