As a kid I used to get my pocket money on a Friday afternoon, so would go straight down to the model shop round the corner to my parents house and buy a kit, usually Matchbox, as they only cost 75p, leaving me 25p to buy a tube of glue, or a pot of paint.
Build time including paint:- 1 hour.
Alright they weren't great, but with Hasegawa's 1/72 FW190, you should be able to produce a neat model in a weekend no problems.
The quickies are break from the larger projects, especially when all not progressing well, and at least allow you to see something complete and sitting on your shef in short order.
