Worth getting? Depends, what are you going to use it for: hunting, plinking, Appleseed, etc? I bought my son a 20g shotgun/.22lr combo; he shot trap with 20g before moving up to a Remington 1100. He put ~500 rounds through the gun without any problems. They are built solid.
I'd save a bit more and get a Bolt Action. Mossberg and Savage have some budget models that I've seen at big box stores for ~$300.00 on sale.
I have been hunting with a Rossi in .243 for several years now. It actually was given to my sons by my Dad. It has taken more deer than any other gun we own. I find it reasonably accurate and haven't had any trouble with it. I think my dad paid about $200 for it, came with scope, rings and a hard case. I think they are a good deal for the money.
I have a Rossi .223 that I built up for long range (well reasonably long) target practice and deer/varmint hunting on trips out of state. I love it. My wife loves it more. Only have it up for trade on armslist lately because my wife's pregnant, and she said she'd prefer me trade than buy. But she really doesn't want me to get rid of it. It's a sub MOA rifle. Rossi in general is really pretty accurate if you get the bull barrels, so that the welded on lugs and hinges don't effect the trueness of the barrel as much.
