Taken as a whole line, Red Max is the best hand held brand of equipment out there, with whoever is in second place a good distance behind them. We sell about 150 units a year and pretty much write ZERO warranties. Their strato-charged engine technology is far and away the best emissions soulution I have seen with very little impact on weight and no negative effect on performance. The EBZ8000 backpack has no competition period.
As far as saws go, the quality is there as well. The only thing lacking is that they don't offer much of a complete line in the US. The 6200 is the largest saw and is an older design. Great quality, but I think a bit heavy for it's engine size. The G3100 is sourced from EFCO in Italy, which is no problem as I think EFCO makes good stuff. I believe that as they introduce more strato-charged engine families they will fill out the saw part of their lineup. The engine on the EBZ8000 would make a great foundation for a killer saw.
It's a little like Dolmar in that it is well known and respected by pros, (primarily landscapers in this case), but the average homeowner is unfamiliar with the brand. But when you tell them that Red Max is owned by Komatsu, they seem to have instant respect for it.
I can't say enough good things about them. Go for it. You won't regret it.
