Used but recently stripped and re-seasoned Lodge 5 8SGP Grill Pan. Late 90's production, just before Lodge began selling cast iron pre-seasoned. I have an outdoor grill that I use for three seasons so this piece is redundant for me and rarely used.
If you do not have an outdoor grill or can't live without one through the winter, this is not a bad alternative for hamburgers and thick steaks as long as you have good kitchen ventilation, or use it anytime for grilled cheese sandwiches, vegetables and/or paninis.
