OK, old fart here, years, no, decades in the business.
Don't buy the Wen!
Oh, yeah, if you are going to use it once or twice a year, ok, but that's about the time it will fail.
You appear to be seeking an "obital" type buffer, you seem to be tending towards starting to do some detailing work on a semi-basis or moving toward a more regular basis, based upon your post.
Should your vision move forward, you will find that you will require a rotary buffer and all that goes with it as well, a pressure washer, etc, etc.
My advice, either go with the PorterCable, which is a reasonable price, as it last for years, or get a name brand orbital, many out there, you don't need to buy those which are on many detailing supply web sites.
Most of which are just "re-branded" versions of brands that are known.
Home Depot, Lowes, etc offer many choices.
What you "do need to think about before buying any" is this.
Does the selected machine allow you to change to various pads?
Can you put a micro-fiber or cotton polishing bonnet on it?
Can you use a foam or wool pad, using a velcro mounting plate?
Are such backing plates available for the unit should you need to obtain them?
Is the unit you are considering be one that has a history of longivity of use?
Should you experience a problem with the unit, is there a service center with in your area?
Not too many people have made a good living if they don't invest in good tools to do their chosen trade.
You wish to "break into the detailing trade"?
Does that really mean you are going to do so "full time", or just a "part time hobby" sort of thing?
A start up cost, for starting up to do a legitiment detailing business requires a lot of good equipment, towels, sprayers, applicators, etc.
No less than $500 to just get going.
Most will say that no less than an investment of $2,000.00 is required to operate a full time business meaning tools, chemicals, etc ,not including insurance, building or vehicle.
Plus, what is your "true knowledge" of what it takes to work with a customer, diagnois paint,trim, etc concerns and how to explain them to the potential customer?
Do you understand and accept that in many cities, etc, a license to do such business is required?
That it is very important that you have business insurance for such?
Do you know how to create or source business documents in order to present a professional business approach, let alone deal with the various taxing portions of your local, county, state and federal agencies?
Not trying to discourage you, please do not take this that way!
What I have posted to you is just the tip of the iceberg, sure that many on here who make a living at this industry on a daily basis will chime in, listen to them.
Just laying out "part" of what it really takes to do a professional business, one that does not end up jumping up in a year or so and bite you in the hiney.
