I've got an RWS model 48-B. It's just like the model 54 stated above, but a little less expensive and not as fancy. The 54 has a Monte Carlo stock and has some checkering.They say they shoot 1000+ fps, but they really shoot closer to 860-930, depending on pellets used. I got mine for $250.00 I think. Extremely accurate and very powerful. I killed a good sized possum with it in the back yard. One shot.I also have a .177 Benjamin Franklin, predecessor to the Sheridans I believe. It's a good gun, but loud. I also have a Crosman 2100. It shoots about 700 fps. It's fairly accurate (alot of plastic), but it's only about $50.00-$60.00.

I guess it depends on how much you want to spend. The Gamos are from Spain, but some models are manufactured in Indonesia I believe, and their quality-control is terrible.

I'd say the RWS Diana model 34 is a good bet. Not too expensive, powerful and accurate. It's a barrel-break design and they last for ever. You can find them for less than $150.00 and your grandkids will enjoy it.
