Quick answer ................... Yes
Better answer. It will all depend on what you want to cook, where you want to cook and how much room you have.
The Q100 is totally portable and can be used without a stand. It will cook for up to 6 people at one time (depending on what you are cooking. It is 9600 BTU which is ample heat for the size, however I found that I need to have it on high for most cooks. Because of the low profile you are restricted slightly as to the size of the roast. It is extremely gas efficient so it is very economical to run.
A comparison against the Q200 series
Q200 - larger cooking area. better temp control, higher heat, higher dome lid, temp gauge is available in Q200, can cook a larger variety of dishes, will fit both the weber veggie and grill trays, comes with 2 side tables (Q100 does not come with side tables - Q120 does). Q200/220 can cook for 6-8 people
Q100 has smaller transport footprint, uses slightly less gas and weighs less.
Q300 is a stationary BBQ and can cook for 10 - 12 people.
Q series is an awesome BBQ range and whilst not idiot proof makes it easier to cook on.
Preheat time for all models is 10 minutes.
I own a Q220, I bought a Q120 for my son and demonstrate cooking on the Q300 this season
I hope this answers your questions, if not post them in this thread and I and/or others will provide additional info.
