Interesting to see bigger routers now coming in cheaply. Formerly it was mostly the less powerful ones.
I take Dominik's points, although most are fixable and if your budget is tight, it's affordable and the cost of fixing it if necessary can still be worth it. It's obviously not for someone earning their living from it, but if you use one once a week and even then not continuously and need a bit of power, I'd say it was worth a go.
Over the years I've had a lot of s/h or cheap machinery that for the sake of a couple of hours work has become worthwhile kit.
A good example were the cheap metal cutting horizontal bandsaws that appeared from China 20yrs ago. Parts of them, like the bearings, vice and stand were poor, but hobby mags soon ran articles on how to upgrade them and an afternoon's work turned them into something very useful, at a time when anything comparable was three and four times the price and most of us wouldn't have dreamed of buying.
Cheap power tools have transformed home workshops. 50 years ago a lathe like a Myford was a couple of month's wages and magazines of the time were full of articles showing you how to make it do the job of a lathe, milling machine, drill press and press tool, in the same way that not so long ago, you could get all sorts of accessories to make your power drill do everything. It was obviously very inconvenient, particularly if some jobs needed switching back and forth between adapters.
Nowadays, we all have a string of dedicated tools at prices, which when compared to wages, are way cheaper than 50 years ago and enable us to achieve things undreamed of then.
I'd be interested to see whether stuff is still as cheap in five years. Much of the availability has been from cheap economies. I bought an East German lathe, when East Germany was desperate for hard currency. The engineering was good. The switch was crap but hey, what does a switch cost?
These days it's Chinese stuff, but as the Chinese standard of living improves, costs will rise and their home market will absorb more. We are running out of cheap countries to get stuff from. I can remember cheap stuff from Hong Kong, then it was cheap stuff from Japan, then the Japanese got into R+D and started doing good stuff, so Korea was next. My car is Korean, I've a Hyundai Santa Fe and it's better than any British car I ever owned. The Koreans have moved on. Now it's China.
Just because something is dear or cheap doesn't matter the way it did 50 years ago. Cheap tools truly were rubbish in the old days. Unfortunately a lot of dear stuff now costs very little differently to manufacture from the cheap stuff and the difference is QC and marketing. Expensive tools probably get individually checked by the QC guys. Cheap ones get every hundredth one checked. The odd dud might slip through.
There is a market for dear tools. A lot of people don't feel happy unless their tool cost a lot. The marketing boys know this and a lot of top end stuff is no better, just dearer, to meet expectations.
Ownership of so called quality brands can change. New owners look to squeeze extra profit out of them to cover their purchase costs. The prices don't come down but once the bean counters have run their slide rule over it, castings get thinner. metal becomes plastic, etc., Some of it is not obvious because technological developments offer improvements at lower cost, but things like service levels and investment in spares availability go. Just because a brand is good today, doesn't mean it will be good tomorrow.
Personally, I've invested in a mixture of tools, even if I can't really justify them yet, because I've a feeling that in the not too distant future, they will be unaffordable again.
