LittleJerry,
I have never handled let alone shot one of the lower priced so I can't say. They may very well be accurate or they could be a piece of junk, I just don't know so I wont recommend any of them. I have owned/shot the following models - 99, 97 25, 50/51, 21, and 40.
Most of these are clones of European made air guns. The 99 is a clone of the HW97 while the 97 looks like the HW77 except for the stock, the 40 is a clone of the Air Arms TX200, the 50/51 is a clone of the Daystate Huntsman, The 21 is a clone of the RWS 48, and the 25 is a clone of the HW95. All of these are accurate and powerful. Lawdog
