Ah yes, the price tag... What should grills cost?
The charcoal grill generally is the least expensive grill, the gas grill the pricier choice. You might want to consider a "price per use" formula to arrive at the price you want to spend.
If the grill lasts five years, and you anticipate using the grill three times a week in the summer and fall (five years times five months times four weeks times three days equal 300 uses), paying $600 comes out to $2.00 per use.
