That looks like a decent BBQ, you will get some great meals from it. Do enjoy!
Personally, when I went from the little green bottles, or even a high pressure hookup, to a low pressure QC system I was thrilled. No more running out of propane in the middle of cooking, no use of a very poor environmental bottle, and no need to store the bottles.
I use the LP QC for my BBQ, stove and firepit, and any two at a time.
Some will worry that the hose is a hassle on the ground, but in 11 years of using this system we have never found that.
I do take along a regulator with hose to use with a trailer bottle should be decide to us an appliance far from the trailer, but have never done that camping. The only time I did do that was for a tailgate party at a football game. I will probably pull the hose out of the trailer.
