Hello grhahun,
I emailed the producer of the TM20LV (superseded is seems) and he mentioned the TM25LV is the update.
He mentioned Engineering Tooling Supplies in QLD is his partner dealer. The mill that looks most similiar is the WMD25V and seems priced competitively. Just thought I'd provide some information from what i've gathered.
Let me know how you go. I'm also considering the WMD25V.
