Confused about Dust Collection

I'm getting very confused about the dust collection options. I've seen 1 hp wall mounted units, units with a big filter on top and bag on bottom in sizes from 1hp to 10+hp, units with cyclonic action before the filter and bag, shop vacs which seem to have as much power but much less airflow, and cyclonic add on's to shop vacs.Then there are supplementary filtering units and all of the units come in different specifications from 1 micron to 30 micron with 2-2.5 micron seeming most common. However, those measurements don't give percentages or how they decay over time.

Prices are also over the place. Shop vacs from under $100 to over $600. Top filter units from $250 to thousands. Cyclonic units seem to start at $800 with Jet having some add-on that they claim does a similar function in the same price range.

I'll need to handle one tool at a time. The tools will include a table saw (probably 3hp cabinet but possibly 1.75hp contractor), router table, miter saw, jig saw, handheld router, belt/disc sander, and, maybe circular saw.

What do you recommend? Will a shop vac with Oneida Dust Deputy cyclone be sufficient? Is an air filter needed in addition to the dust extractor?

The workshop is in the basement.

I am still paralyzed on the subject (google the subject and you'll find 10 people expressing 20 opinions…they can't even decide in their own heads). I guess my biggest question right now is ease of emptying. Bags look a little messy.
Bert…from what I've read (I am still in a state of "no action"...happy to see that I am not alone in my confusion), sounds like the plan is to collect as much as possible at the source. the air cleaner comes into play for the stuff you miss that becomes airborne.

I'm going to start with the first step and probably add the second step. I have radiant in-floor heat and I'm positive it creates goofy air currents that send the fine dust everywhere. Shop is 30'x40' I have relocated all the tools to work in about a 15'x 20' area but still find dust everywhere.
for home shops without DC, I think it comes down to "how clean"? we have been surrounded by dust forever so even a cheap solution is better than none (e.g. in my case no known problems other than a bad back from trying to keep my floor and surfaces clean).

the problem I have with relying on filters is that they don't take long to clog up and the process of cleaning them seems to drop a pile of sawdust everywhere. like 4 steps forward, 1 step back.
