See i'm debating whether or not just a big kettle BBQ would be sufficient to dip my toe into the world of smoking as you can still smoke in them as opposed to buying a specific smoker like the ProQ Frontier.
The other downside to the ProQ Frontier is that if I wanted to use it solely as a BBQ rather than a smoker it would sit pretty low on the floor, whereas normal BBQ's tend to be a lot higher.
You can do a fine job with a half-decent kettle BBQ so if that's a major concern then go for it.
If you want to make things easier for yourself on that front you can also just transfer the low and slow stuff you're cooking to the oven after it has had a few hours of smoke - the end result will be almost exactly the same.
