Hello,
I have just restarted in modeling myself, oddly enough I built a Corsair.
From my recent experience I would recomend choosing the model first, then acquire supplies. This way you can purchase paints as you need them, without having a large cash out lay at the start.
Somethings you will want to purchase all at once are:
A xato knife is a must.
I used the old faithful tube glue to start with.
Brush wise, I started with the cheap Testors white plastic handle ones and can honestly say, avoid them. For a buck or 2 more, you can get some really nice brushes that do a much better job..
Some sort of sanding item would be nice also, sanding boards are really nice, but you could use the black faced wet-sanding paper from the local hardware store if you wanted. I happened to have some of the sandpaper laying around from a furniture refinishing project, so I used that, I have since purchased sanding boards.
I hope this helps, and good luck!
