Most of those guns are pretty simple to repair, and there are kits out there avaliable to repair if something does come up. it does take quiet some time for them to get in a state where repair is needed, but it can happen. You should be good to go with the remington, i wonder who they are importing it thru, most the firearm manufacturers are importing another dedicated air guns companys gun and calling it theirs.
if it doesnt come with a scope, make sure you get a scope ment for air rifles. they have a very strange recoil that absolutly destroys centerfire scopes. my old break barrel gun was fun, i wouldnt mind getting another, but i would prolley go ruger or gamo if i went with one.
