Sounds like you're well on your way. Lyman & RCBS = darned good lubrisizers. I use them both, plus a Saeco.
I've never had need of a heater over 50+ years of casting bullets. God only knows how many hundreds of thousands of bullets and nary a need for hard lubes that require a heater.
Agreed.I've not seen the need for lubes that need a heater over the 4 decades I've cast bullets.
I make my own lube and will sometimes add a bit more beeswax in summer months to firm it up but it still flows well.
The only time I heat my sizer is in winter when my shop gets too cold and then it's just a light bulb over the thing an hour or so before I lube.
