How inexpensive are we talking about here?
I've always had a soft spot for Finnex. They are a little more expensive than other "Amazon tier" lights (nicrew, etc.), but I find their color tone to be much more pleasing than the other options. It looks like their newer lights have built in controllers and I have no idea how those work. I would hope they are an improvement over the old remote system at least!
The WeekAqua M series is the cheapest of the narrow band RGB lights I know of. That's more expensive than any Finnex, but it looks a lot nicer.
