Cast Iron Skillet: Purchase and season new by Mom

I've been wanting to buy a cast iron skillet so here's what I found:

When looking to purchase a cast iron skillet: look for helper handle on far side of skillet because it's a heavy pan.

Some brands come pre-seasoned but if they don't, you have to season it.

Drizzle oil on bottom of pan. Use a paper towel to wipe around everywhere inside pan. For even seasoning, invert on baking sheet (put upside down). Put in oven on 250 degrees for several hours or all day. When it is done and cool, the surface is glistening and non-stick. Every once in a while, season your pan again.
