I have the 541THB (the heavy barrel variant). I'm not up on their worth but they are a decent .22, no longer made. Some have the bad habit of throwing the first couple shots out of a cold barrel. Mine does. Subsequent shots group pretty well, so it's useful as a range gun where I just dump the first couple shots off the target. What really bugs me about the 541s are the cheap plastic magazines, but I came across a guy who made metal mags for it and bought 2. Those plastic mags are an abomination.
