depends on what your planning to build, the difference between large and small shank should not be of concern unless your building something big in the magnums, and that extra little bit of metal around the chamber is very little gain when you think about other rifles such as Remington building magnums on almost the same shank size as the small savage.
Take off barrels in large shank are no where near as common as standard shank barrels are, this only comes into play if you are building a switch barrel or what to experiment with a bit of everything. Your basically paying for a repeater action that your likely going to invest into a after market trigger for, so add in almost 200 dollars more, now your at 600.oo and no barrel, if you want the solid rigidity of a single shot then your almost at the price point of a target action, no trigger upgrade needed, just a barrel and a stock....
But without knowing what kind of build or purpose you have in mind it is hard to steer you in any direction, all we can do at this point is spin you in circles and leave you wondering, possibly even more confused then you where before you asked the original question....
