We've had this outstanding little Weber portable grill for at least 15 years and now carry it in our motorhome. Indestructable and it can sear steaks just fine. The heat can be adjusted to any level. If it ever does need parts to keep it going, they're readily available. You can even fit a couple of the 1 lb. propane bottles right under the lid for an ultra-compact little package including the spare gas. We even use it to backup are large ~25 year old Weber at home on the deck.
With a Weber you're not buying merely a "BBQ grill" - you're buying "ongoing BBQ'ing capability" for a lifetime:
