I meet your criteria as a sole shop owner. I replaced a Powermatic 12" planer and a Grizzly 8" joiner with a new Hammer A30 12" combo planer/joiner. Hammer, the less expensive brand of Felder, has worked well for me, and I believe they ship to Canada (US Delaware location). It has taken everything that I have fed it, as have the other machines, for that matter. It converts easily between modes (30 seconds) and has indexed HSS knives that are reversed when dull, and then disposed of, perhaps 10 minutes to change over the knives. I have never had curly maple plane better than on this machine. 15 years and still have replaced nothing other than the knives.
I use a space on my residential property as a shop, so 3 phase was out of the question. This single phase machine has been trouble free for me, perhaps because I am the only person using it. The smaller scale machinery is adequate for a one man shop, unless you are doing millwork of a size that is scaled for a castle.
Conference tables, paneling, entertainment centers, furniture pieces, moldings, doors, windows and cabinetry have not been an issue with my "underpowered" machinery. I have a 3HP Unisaw (Rockwell, before they became Delta again) that I bought new, and in 35 years of daily use all I have replaced are the arbor bearings one time. It rips 8/4 oak without bogging down.
I think that the criteria for purchase should be comfort level with the machine, space requirements, affordability, ease of maintenance, and having it be a good fit for the type of work you do.
Everybody likes the bigger toys with more horsepower, but for cabinetry/furniture/small millwork, the single phase "cabinet shop" machinery has proven to be adequately powered and has served me well. For my work, I don't run machines all day long. There are enough people like me buying these machines where resale should not be an issue.
"Underpowered" machinery has yet to be an issue; since I am on in years I am usually the one who is underpowered.
Hope this helps.
