Keep your eye out for an older 8 inch hitachi....you can pick them up for around 250 -400 but they are arguably the best saw in thier class ever made.
Nothing you buy new comes close to them in quality
Mines around 25+ years old and still going okay. I got it 2nd hand and used it daily for 10+ years, mainly for cutting aluminium.
Good saw, but noisy and the guards are complete and utter rubbish. I thew about 3 new guards at mine and gave up in the end. Rubbish 3 piece plastic set up.
The guards on those era Hitachi's (8" & 10") were so bad Hitachi ended up doing a full recall on all the old CF models about 6 years ago. Just had to take your old saw into any Hitachi dealer and they would give you a brand spanker for free! I found out about the recall 12 months after it finished
.
My current saws a 12" Metabo SCMS, the previous model which is just a rebadged Elektra Beckum. Beautiful saw to use, smooth, quite and great depth of cut on compound mitres too. Only thing I don't like is the trenching stop is a bit flimsy.
The LS series Makita's are brilliant too. We've got quite a few of the 8 and 10" ones at work. The LS1018 with the dual slide rails is a great saw. As others said not as good as the previous models that were Japanese made. The older Japanese LS1216 with the vertical handle was the best.
Makita, Hitachi, Dewalt, Metabo, Blue Bosch. Can't go wrong with any of them, all comes down to what feels most comfortable for you.
