the key is not to over spend when starting out. Many have suggested the WSM and OTG combo to start. That is what I did. I realized quickly that the WSM was not what I was looking for and got really lucky selling it without losing my shirt.
Start with a kettle, learn how to Q with the basics. The OTG is the most versatile tool out there as far as I am concerned. The 22.5 is great but the 26.75 would be cool as well.
If you hate it you only have a few hundred invested.
One poster already stated about the egg. I wish that I would have saved a bit more and then purchased. I am saving for the kamado Joe Big Joe. it is exactly what my cooking needs require.
Remember many here on the brethren have been at this a long time. The only thing better than spending on this hobby, is telling others what to buy. Dont get wrapped up in the hype. Start small and see what you think before purchasing something that you will wonder how the hell you can sell it later.
