I own 3. 1 MKII Hunter stainless that I paid 250 otd. The other 2 are MKIII 22/45 which used also cost me 250 otd and my very first gun which cost me around 300 new at the time.
You should just get them used and in good condition. They way they are build, you would have a hard time breaking them.
You will find them used from 200 to 300 in good to great condition.
