I have a corded WEN. It works for carpentry and is quite handy. As far as I can tell, it works as well as any more expensive one. I think WEN is the champ for cheap tools, but some of the newer HF stuff is getting quite good. I've used it to knock down rough sawn, but in reality, my scrub plane does almost as well with little more effort. I think the Makita is considered cream of the top. Most of the time, it is easier to grab the hand tool that drag out the power tool, plug it in, hook up dust collection.... For small parts, you would still need to have them secured somehow. Just as much work as double stick-ing a small part to a bigger block to run across the jointer.
Even if you are a machine woodworker, a good old Stanley Bailey #4 type 14 through 16, any old cheap POS opened up as a scrub plane, an a old #6 or #7 and a router plane should be part of your kit. Oh yea, an apron plane. I love my horribly expensive L-N, but there are many others. Just too handy to knock off an edge or trim a little here and there. Far easier than setting up a router just to ease an edge. In a lot of cases, it is easier and quicker to do it by hand. If you have 100 to do, that's another story. I am not adverse to power, just am old enough to know they are not always the easiest way.
If any operation on a power tool scares you, just don't do it. Back off and think how it could be jig'd . Personally, I am rather "attached" to my fingers.
