3400 with 24" bar and full skip. 3800 with 20" full chisel. Both have received maintenance: fuel lines, carb kits, tune ups, simple parts replaced. Run great, and look spec-tac-ular. I got the 3400 for 100$, tuned her up and slapped on some cutters. Got the 3800 for 30$, some minor fuel and carb stuff, now she idles like a lioness. Never thought I'd like these saws as much as I do, just can't explain it.
