Hi,
I am upgrading a 2.25hp router on my 4848 CNC. I see many Chinese spindle/VFD combos, Vivor, Jianken, unbranded etc.. What I do not see is user feedback here or anywhere else reliable as to each one's likelihood for meeting spec, meeting runout, lasting, etc.


Can anyone recommend a 4kw spindle kit in the sub $1400 range?
Can anyone find belt drive only spindles in the USA, such as this one :https://www.jian-ken.com/mechanical-...l-spindle.html ?

I may consider the Avid CNC 4hp one, it's $2k and only a little more than I wish to spend on this, but wish to explore the viability of these budget ones first
