I think you get as big as you can fit and afford. I needto head over to Costco to load up on pellets.

Definitely don't have room for both a larger Traegers and the Keg.   I think I might try giving the Smoke Daddy another chance,  this time I'll use all pellets in it instead of wood chips. 

Update on my Smoke Daddy.  I've had problems with pellets not maintaining burning and going out in the middle of the cook and I've had to relight it a lot.  I ended up leaving the bottom open and putting an ash catcher and ceramic tiles around the bottom area, and put a small fan to direct a little bit of air to feed it.  Worked really well.  Too well, in fact with pellets, really burned through them fast.  So I tried smaller pieces of apple wood chunks, since there are a lot of smaller chips, slivers, and small chunks in a bag of wood chunks that go to waste normally.  So the forced air fueling the Smoke daddy with solid wood chunkettes seems to work the best.  I got a really nice smoke ring on my last Pulled Pork smoke. 

 

It does get my Smoke Daddy blazing hot, though, so hopefully it holds up to this method.  It's kind of a miniature offset smoker this way.  If I had it to do over again, I'd have a coffee can sized smoker attachement made from Stainless steel rather than a thick aluminum tube the size of a pint glass.
