To adapt a rule from the computer world to reloading scales: Cheap, Digital, Quality - pick any two.
That said . . . +1 for a beam scale. We all have access to laboratory grade gravity, and with a little care an RCBS or Dillon or Lyman (all made by Ohaus, as were a few other brands) will give excellent accuracy and repeatability for a very long time. (If you have the Lee scale and like it, so be it. But I've used Lee presses, dies, primers, case prep and most of the other stuff he makes since I started reloading, and that little scale is the one Lee product I have actually just thrown in the trash. It didn't begin to compare in convenince to my RCBS 5-0-5.)
A few of the 2-poise beam scales can be tuned up by a guy named Scott Parker, to respond consistently to a single grain of stick powder added to the pan. He doesn't work on the 3-poise models, saying they don't tune up as reliably, as I learned when I asked him about going over my 25 year old 5-0-5, which is a 3-poise scale. In the course of that exchange he said that the old Lyman M5 (a 2-poise predecessor to the RCBS 10-10) is the finest beam reloading scale ever made - I believe he said it was "superior in every respect" to the RCBS. (BTW, Mr. Parker will NOT work on the newer RCBS and other scales that are now made in Mexico - presumably because of quality control problems that the older US-made models just didn't have.)
Based on his comments I went looking for an M5 on ebay, and got one for $90 (delivered) not too long ago There were a couple of others that went for $75 or less at around the same time. Mine responds to each grain of Varget added to the pan, without a tune up. If you're not in a big hurry, you might keep an eye open over there. Even if you don't want an M5 there usually are a lot of other used scales that fit completely within the stated budget.
