I'll secong ASPI for good prices on SpeedFeed stuff. I bought my SpeedFeed III Tactical stock set from them last month. BUT - I don't know about the "will ship same day". I was told when I ordered that the set would go right out, but it still took two weeks for it to get to me in Arizona via UPS (no "wait for check to clear", I paid by credit card).
In my experience - Good merchandise, good prices, but a bit slow on the delivery. Overall - Yeah, I'd buy from them again.
