Dunno if it fits your price range, but the Weber Genesis and Spirit series grills are truly awesome products for the money.
Watch for sales at both the beginning and end of seasons for spectacular deals on Weber grills.
Weber grills tend to last for years, have relatively low maintenance, and are very well supported even decades later.
The Genesis is their bread and butter product line. Home Depot has carries the only Genesis with cast iron grill plates.
A little advice when purchasing ANY brand of grill.
1 - Get the heaviest grill plates you can find. The the thermal mass is paramount for searing.
2 - Consider having two propane tanks. Sucks to run out half way through a grill out.
3 - Get stainless burners if you can.
3 - If you get cast iron burners or grill plates, season them. (

4 - DO NOT get anything with lava rocks or their like. They are a nasty mess that constantly cause flare-ups among other issues. Though they are a huge improvement over lava rocks I am not a fan of the ceramic blocks either due to similar issues.
5 - Keep an extension lighter on hand. Inevitably the piezoelectric lighter fails. (I seem strangely immune to this...)
6 - Cheap wire frame grill plate grills with galvanized steel burners suck. They don't sear well, rust easily, fail constantly heat unevenly and are expensive to maintain. IMO If you can't afford anything else...my advice is to wait until you can.
Hope that helped.
