I've got a couple of perspectives on this.
First is going with a CT Mini and a Dust Deputy. Suction is the same on all the CT's so the mini would do just fine, but adding the dust deputy would give you an inexpensive way to deal with the chips/sawdust generated from the Kapex without chewing up bags.
Second would be a CT 36 or 48. Same suction but now you've got more capacity for chip/sawdust collection.
A third option would be a CT 26 with a LongLife Filter Bag. If the LongLife bags for the Mini/Midi were available in the US, I might go that direction, but that's not currently an option.
And, of course, the 36mm hose. Preferably, a shortened one as to not waste a long hose and have to have space for it.
Personally, I'd probably go with the CT Mini and the Dust Deputy unless I could get a LongLife bag for it.
Just my $0.02.
