I have the one below. It is plasticky and cheaply made but does the job. The soap dispenser is finicky and I don't use it. From memory, I paid like $100 on deal direct from Sun Joe with some coupons.

If I had my time again I'd probably get one with a reel for convenience. Something like this:

Personally I like a relatively low power (1500-2000 ish PSI) because there is less risk you break something, strip paint, put holes in your plastic floor mats etc.
There is a use case for a more powerful unit if you buy an undercarriage sprayer with multiple nozzles such as this:

I get on my a creeper and use this to get into nooks and crannies when doing my undercarriage. Dirty work but someone's got to do it.

Don't spend big money on a snow foam cannon. A cheap one is fine. IMO foam is a gimmick with the only real benefit being increased dwell time. (Soap doesn't fall off as quickly).
This is also an interesting new development, battery powered one but I haven't tried it myself.

I would love to have a hot water generating unit but they are nearer $2k.
If you want to splash for a top of the range cold water unit look at Kranzle.
Maine mud is no joke.
