Weber all the way. I have 2, a NG & LPG genesis. Love having two. Can cook things at different times and heat settings and still all ready at the same time. NG isnt as hot though so better for roasts, chicken, and other indirect cooking stuff. LPG used for steaks etc. And get a side burner, awesome for turning leftover marinades to a sauce. Have a spare lpg bottle and running out never a problem.
And Weber after sales service is great. My electronic ignition died after about 6 yrs, long after warrenty ended, they just sent me out a new one. And my flavouriser bar rusted cause i use a lot of marinade and dont clean them often. Sent me out some more, no questions asked. Mind you that one was still in warranty period.
When looking, check out the weld quality. Cheap ones are only tack welded. And give the thing a good shake to see how flimsy cheap ones can be.
