I know this isnt exactly what you are looking for (considering price) but since you are looking at semi-auto .22 WMRs, there is really
only one quality answer that I am personally aware of (but someone might have another suggestion):
Volquartsen CustomThese guys really picked up where the 10/22 Magnum left off, and they created some very fine semi-auto rimfire rifles. They are quite similar in design to the Ruger, but they have gone far beyond the Ruger by fixing the quirks that the 10/22 Magnum had, and put higher quality parts in it as well (springs, sear, trigger, etc).
