Eastwood has some good stuff. I've bought things from them for many years. They have always shipped faster than most other vendors. My experiences with customer service is a little less than stellar, but everything I bought has been good quality.
They have a great line of buffing supplies and I've used them quite a bit with very good results. Right now I'm buffing the stainless trim from my Chrysler using their buffs and compounds with a Harbor Fright buffer. Eastwood sells a Baldor buffer and their own brand. The Baldor is... well... a Baldor and I would expect that to be very good. Eastwood's buffer looks like a HF buffer with blue paint.
The have a decent line of rattle can products and I understand their rust paints are as good or better than anyone else sells.
I'd think twice about buying tools from them. From what I've seen, most of their tools can be sourced elsewhere at cheaper prices.... and with cheap tools, you get what you pay for.
