I've found Irregular to be not unlike (though not quite as "plain" as) Peter Laing and Editions Brokaw. They tend to be true to their size - no "heroic" 28mm (ie 35mm) here - and so can look a little small beside other stuff of (allegeddly) similar size, and they have as much/little detail as is needed to broadly identify the figure, but you can always add more if you want. And very inexpensive, and sold by nice people.
Also, their animal sculpting skills aren't half bad - the assorted wildlife looks like what it is supposed to be and is reasonably in scale with its human owners/pets, which is more than some manufacturers can boast.
