Eastwood body saw

Okay so I get an F for first use of this body saw. I couldn't get the cut started, then I found out why when the SECOND allen screw popped out of the side of the saw. I'm used to my Makita Sawzall that only has an allen on ONE side, so when I installed my blade I only tightened down one side (I guess that's why it happened). Anyway, China blades will probably work, but am looking for recommendations for replacement blades, Milwaukee? Here's some pics of my replacement patch panel prep work today, too many beers to proceed (to the hardware store) HA!
