No more time and money than any other ported saw, except the extra $100-$125 for the 357 parts. Like has been made clear here, it's not required for building a super strong 346.No Brad, not to that level, but how much time and money do you have wrapped up in that thing? What would it cost to have one built? What do you think the longevity of it will be? Is it useful for more than cutting cookies? I'm just looking at the practicality of it, the usefulness vs. the cost factor.
And no, I'm not wrong, I've done both, run both and I still have the 350, but I like my 5100 better than either of them anymore.
