No point in buying such junk when the excellent Lee Classic Cast press is available at a reasonable price. My copy is perfect as near as I can tell and beats presses over twice as expensive on strength, precision, ease of use and features. I think it set me back $57 when Midway had a sale.
I can't say about the scale? The $30 ones get mixed reviews which make it appear some units work a lot better than others. Not consistent, so it is catch as catch can as to whether you'll get a good one or not? About the cheapest one I've heard consistent good reviews of is the $75 scale that Brian Enos sells. There is a version around at half that price, but the cal weight and capacity are half what Enos's version has (50 gm instead of 100 gm)) and it doesn't carry the 20 year warranty Enos's scale does (the only such warranty on an electronic scale that I've ever seen). From the maximum weight difference I would guess the same company makes them with the same electronics, but with different load cells. Unfortunately for bargain hunters, the load cell is most of what makes an electronic scale good or bad. One could be an inexpensive capacitance cell, replete with drift and whatnot, while the other might be a real strain gauge cell? No way to tell without dissecting them. I know Enos's scale has had good reviews. It's probably the cheapest one I would be willing to try if I needed another electronic scale (only have four now, if you count the old Lyman 1200 that doesn't work anymore.
