WAIT! Don't rush. Recently I included this product as part of a discounted deal I created. Take a look at it. It might be the discount you were looking for: http://crtv.mk/axvt
What you get are 600 hand-crafted icons, carefully designed on a 16×16-pixel grid, sharing the same visual language. Inside you'll find generally used pictograms as well as icons for eCommerce, business, electronics, weather, emoticons etc.
Photoshop: Included are 6 files, in which there are 3 sizes: (16×16, 32×32 and 64×64) and 2 color variations (black and white). As long as you keep the progression of doubles, you can easily get 128×128, 256×256 etc, without sub-pixel rendering.
Vector: Limit? There is no size limit. If you aim toward really big ones, you are equipped with AI, EPS and SVG files versions as well.
Transparent PNG: For web use, you also have all the icons sliced individually in PNG 24-bit format. Included are black and white variants for each size, 16×16, 32×32 and 64×64, which in total turns out to be 3600 icons.
If you like the icons but don't like this style, check out the solid version: http://crtv.mk/hfa7
Or in case you want both, stroke and solid icons, I have that covered in this Ultimate icons pack with a discounted price: http://crtv.mk/sW1C
