Hi, Swifty:
I can't really suggest anything about the old 45, unless you can seal it up with some o-rings. Any farm or industrial equipment shop or automotive specialty store should have an o-ring kit with dozens of sizes to pick from.
Generally the RCBS is preferred to the Lyman 450, as it's stronger and has a better bottom lube chamber seal, although I don't see anything on my 450's linkage that isn't fixable with some grade 8 bolts. The new Lyman 4500 may be your best bet. It has a better bottom seal, stronger linkage, optional built-in heater and retains the lube piston screw ratchet that RCBS no longer uses, much to the annoyance of Big Green fans. I haven't used any RCBS dies, but the Lymans are said to be smoother. The Saeco dies are threaded on the bottom and won't fit a Lyman or RCBS.
There's a report that the Lyman 4500 die chamber is reamed undersized and some older dies that are over maximum outside diameter won't fit. Developing.
