Pixel Logo – Premium logo templates. Really good selection. Most premium logos in the $30 range with some free ones too.
Logo Instant – Much like Shaboopie, good site for nice looking free logo templates. Downloads usually available in both PSD and AI.
Logo Open Stock – Big selection of templates, both original and from around the web.
Brands of the World – Huge variety of logos with comments and downloads. Get inspired!
FreeLogoOnline.com – Nice selection of free logo templates, mostly in EPS format.
StockLogos.com – Large marketplace for “premium” logo templates. Big selection but I find them to be way overpriced. Good for inspiration at the least.
Complete Guide to Logo Design – Here the word ‘complete’ might just be an understatement. Highly recommended!
Photoshop Tutorials – Amazing, high quality Photoshop tutorials including lots of logo specific ones.
Illustrator Tutorials – Ditto above but for Illustrator.
Free Logo Services – Online logo maker. You can play around for free. You choose your font, text, colors, and graphics. Once finished, you have to pay to download a high res version. You are probably better off going with a custom design, but still fun.
Cool Text – Old school online text / logo generator. Lots of options, tho they are mostly dated.
All Silhouettes – Whole bunch of nice vector graphic downloads.
Pink Moustache – The name says it all! Wait… that’s not true at all. Still, nice collection of icon sets and original vector sets, including, yes – moustaches.
Shapes 4 Free – Groovy Photoshop custom shape downloads.
