If you're not familiar with GunPrimer tools... where have you been? But seriously, their Raser gate remover tools are arguably the best at removing nubs from your model kits.
G-Rework waterslide decals also offer interesting designs for kits of all grades. The designs are often a bit different than what you'd see from other sets, so you get a little more variety and options for your decals.
