Here are several ideas for lego simpsons, i made them because the simpsons sets are mainly very expensive,
- lego willie's shack - includes groundskeeper willie, his shack and a tractor. I would price it between £17.99 and £39.99.
- lego springfield elementary school playground - includes a few play equipment sets and characters like millhouse, lewis, sherri and terri. Priced between £12.99 and £20.99.
- lego moe's tavern. Includes moe, homer, lenny and carl. £29.99 to £59.99.
- jebbediah springfield statue, includes a salesman of some sort or mayor quimby? £14.99 to £20.99
- krusty burger - includes krusty the clown, one or two customers and the sweaky voiced teen. £50 to £100. Slightly bigger than moe's tavern.
- homer's ice cream truck, homer in an ice cream costume and a few kids like ralph. £25 to £50
- Android's dungeon. Includes the desk and all the comic book stands. There is only the front wall. Includes comic book guy and a few children. £10 to £20
- Cletus spuckler house. Includes the house, chicken pens and a few other farm features. Cletus, brandine, and a few children appear. £50 to £120
I will add more, probably some that can relate to specific episodes.
