I'm with Bryan on this one in that you'd be happier with more HP but, that would most likely require a 220 run.
I vent mine outside and love it most of the time. They only time it creates a "dust" issue outside is if I let the bin over fill. Then, it make a mess! You really don't see any dust during normal use.
The hard piping looks simple enough. If you're able to upgrade the machine, you could go ahead and pick up all your tools with simple blast gates and be done.
I think all the bigs make good reliable DC machines. Suggest some homework to see your options but, Oneida, Clearview, Laguna, Harvey, and Grizzly all have legitimate options. I don't recall the brand of the one @Chet has but, it does a nice job in his shop as well so, would also be a viable option for you.
