Not particularly relevant to the requirement regarding a 315, but I can recommend a Sedgwick for brutal service, I have a Sedgwick TA415, with the large sliding carriage, I don't use it, it takes a up lot of space, I use a chainsaw, radial arm or chop saw for cross cutting, dust extraction is pants,
@deema mentioned that, even with a 100mm & 150mm extractor connections on it) but, its bullet proof for my principal needs in that I rip a lot of Oak, usually 100mm thick (it has a 150mm cutting capacity @ 90), however I also needed a saw that could deal with more refined sections and with the 415 I have to fit a smaller diameter blade with a higher tooth count, but its still an aggressive machine, so, I have invested in Laguna fusion 3, this fits in well with the space I have, has been faultless, and a bonus for me was the blade tilts to the left, away from the fence, (and it'll take a dado stack,
Here, as you said, if you wish to go down that rabbit hole of opinion) down side it doesn't offer a sliding carriage, but I don't need one.
Both machines work well with solid stock, and the Laguna copes well with sheet material, but I would generally knock sheets down to more manageable if not finished sizes with a rail saw &/or on the MFT first, oh and for good measure I also use a little Kitty 419, but that's set up for a specific purpose.
