Yea, if the saw is working good and you like it, get a fish pump. Everyone I know that has a DW788 seems to be quite happy with it. Personally, I found it bulky and awkward, but that is most likely because I am not used to that saw.
I really want to recommend the Hitachi CW40..but I haven't had a chance to personally examine the machine. I know it will be quality as far as being sturdy and well crafted and it definitely will have curb appeal. Those guys at Hitachi really know how to make a tool look futuristic, and their colors are the greatest in my opinion. What I'm afraid of is the blade holder system. I have only seen pics and it does not look like a quick change blade holder. It says it takes pin and pinless blades. When a saw says this, I worry. If it's anything like craftsman and Dremel..the pin holder is a permanent holder in the machine. The pinless holder is a seperate piece that simply slips on to the pin holder and that sucks..it makes for too many connections. Tensioning becomes a problem and if the blade breaks, the holder fly's off the machine. But..it's $170 and comes with a stand, blower, light, speed control and induction motor which is what you want. I know a guy that can fix that blade holder situation permanently..this is what he does. I run a Hawk G4 and it is designed for pinless blades only, which is a good thing, but it is a knob you have to turn to tighten in the blade. I had a set of quick connects like Dewalt uses modified for my machine. Best $100 I ever spent! Now the guy is selling them to other G4 owners. He most likely has the bellows for your broken saw too..should you want a replacement.
