The 48 is a powerful magnum springer and very hard on scopes. The advice is good. You might get away with a cheap scope for awhile, but scope failure at some point is almost guaranteed. A cheap scope sometimes appears to be working fine, but a check for accuracy often reveals that the point of impact is actually shifting around. Getting a quality scope, especially for a magnum springer, will likely save money in the long run. I have "lucked out" with cheap scopes on low and medium powered springers but it is a gamble. JMHO.
